Frequently Asked Questions
CAMEL FAQ
General
On the front screen – File menu > Project default the user can set the default locations, plant operating times, inside design conditions and various storage masses.
On Front screen Menu bar select Shadow [or button]. Now select the ‘Room’ and ‘Surface Number” required and the time and month or even animate it, so it steps through the months at a time of day OR steps through the hours of the day in one month.
Use the comments button on the project tab – Comments appear on the project details output. Alternatively, you can send the selected results to a word document that will allow you to add any comments wherever you like.
Primarily Australian and NZ and also PNG, Pacific Islands, China and a limited number of locations in South East Asia – see the pull down lists on the project screen. Australian and NZ locations are also shown on a map (button on the project screen). Other data (e.g. ASHRAE) can be entered and saved by selecting the second top entry (user defined monthly) in the locations list.
Yes, you can but it is not available from within CAMEL. If you go to the top of the first pull down location list the second entry is ‘user defined monthly’. Once selected, an Edit/Add button appears which will open a new form where you can enter and save the ASHRAE or other weather data.
If you go to the top of the first pull down location list the second entry is ‘user defined monthly’. Once selected, an Edit/Add button appears which will open a new form where you can copy the data from the existing location then change any entries you need to (say +0.5 for all CDB etc) then save the data with a modified name eg Sydney +0.5.
If the Heat Exchange only serves one AHU then it may be entered on the AHU tab page but if it serves more than one AHU then it must be entered on the Pre-conditioners tab page and then referenced on each connected AHU.
Yes. If you set up a chilled water sub-circuit (or more) then various FCU can be connected to the entered sub-circuits and are still included in the chiller total.
O/A can be entered in two places, either the AHU tab, (if a fixed L/S or % of Supply Air is used) OR the Zone & Rooms tab if L/s/person or/m2, air changes or fixed L/S for the room is required.
Yes. If the ‘direct’ box is checked for O/A on the AHU tab then the O/A is supplied direct to the room. If the O/A comes through a heat exchange or pre-conditioner, then this is still applied direct to the rooms.
Yes. This calculation can be selected on the AHU tab page. However, it cannot be used with VAV systems as the calculation can give unusual results and is not well defined in the standard (AS1668). It is usual to do 2 runs of CAMEL – one with AS1668 compartment formula and one without, to demonstrate what the calculation is achieving. Note it will only work if each compartment (as per AS1668) is a separate room on the AHU in CAMEL.
Click on the Red Face and a detailed error message will appear.
Schedules
On most jobs, schedules are not necessary because when calculating peak loads, it is usual to assume all lights and equipment are on 100% and all people are in the space all operating hours. In CAMEL this is the default if schedules are not entered for people, lights and equipment. If loads are not 100% all the time, then schedules should be used.
Shading
The diagrams are indicative only of the shading scheme since the actual shades are a function of the window or wall dimensions (height and width) to which the shading scheme is applied later on the external tab. One shading scheme could and often does, have different appearances as it is applied to several (different sized) windows and walls. The shading schemes are displayed to scale on the external surfaces on which they are used. To see the actual shadows on the surface – view the surface using shadow (button) on the front screen.
All overhangs and reveals (fins) are by default perpendicular to the surface. Angles can be incorporated using the ‘ROTATIONS ’ at the bottom of the Shading tab.
Window and Wall shading on the Shading tab page has a factor for overhangs, drop panels and L & R Reveals (fins). The factor 0 – 1.0 represents the fraction of Radiation which passes through the shade. So, if shade cloth is 50% set the factor to 0.5. [Totally transparent is 1.0 and opaque is 0 or blank]
Chillers Boilers & Circuits
On the Chillers, Boilers and Circuits tab page, Chiller Diversity Factors for people, lights and room equipment (sensible and latent) can be entered (0.25-1.0). This will not affect the AHU peak loads but will reduce the chiller load components for people, lights and equipment.
The user must estimate these as a % of the chiller or boiler load or use other techniques to calculate them as kW.
Preconditioners
If the Heat Exchange only serves one AHU then it may be entered on the AHU tab page but if it serves more than one AHU then it must be entered on the Pre-conditioners tab page and then referenced on each connected AHU.
If the Desiccant Humidity Control Unit only serves one AHU then it may be entered on the AHU tab page but if it serves more than one AHU then it must be entered on the Pre-conditioners tab page and then referenced on each connected AHU.
At this stage, this is correct but since cooling and heating calculations are done independently in CAMEL, set the cooling to what is correct and the heating just below this. The cooling results will be correct but not the heating. Then do another run where you set the heating correctly and the cooling above this, producing correct heating results.
AHU Coil
Whatever is most appropriate and you understand. In either case, it is simply a means to estimate the required Leaving Coil conditions and these need to be checked for practicality and compared with possible unit capabilities. This may result in the need to adjust these values in subsequent runs.
Fan Heat Gains are always a load on the coil but in many smaller units, these days, that are MEPS rated the rating has already been discounted by the fan heat – so act accordingly.
Safety factors are to allow for the uncertainty in the data entered including, variation in weather data, estimates of number of people, equipment in use, wall U-values, wall colours etc. It is the designer’s responsibility to ensure that he has a realistic and honest estimate. CAMEL simply adds together the Load from the entered data then applies the entered safety factors.
Yes. On the AHU coil tab, the Load Chart Printout for each room on that AHU can be set to the Room Peak, Zone Peak or to a set time and month. (The user must pick the time and month – typically the time of the AHU peak.)
Project
On the front screen – File menu > Project default the user can set the default locations, plant operating times, inside design conditions and various storage masses.
On Front screen Menu bar select Shadow [or button]. Now select the ‘Room’ and ‘Surface Number” required and the time and month or even animate it, so it steps through the months at a time of day OR steps through the hours of the day in one month.
Use the comments button on the project tab – Comments appear on the project details output. Alternatively, you can send the selected results to a word document that will allow you to add any comments wherever you like.
Primarily Australian and NZ and also PNG, Pacific Islands, China and a limited number of locations in South East Asia – see the pull down lists on the project screen. Australian and NZ locations are also shown on a map (button on the project screen). Other data (e.g. ASHRAE) can be entered and saved by selecting the second top entry (user defined monthly) in the locations list.
Comfort conditions are based on a 3 pm design temperature which is exceeded on 10 days /year (including one standard deviation) i.e. across the whole year and is typically used for comfort A/C. Critical is the 3 pm design temperature exceeded once in two years in that month. E.g. Jan temp exceeded 5 times in 10 years and so on for each month. Generally used where more stringent design requirements are in place.
The locations where weather data is measured changes over time. The before 1990 data was in an earlier version of Camel, whereas the after 1990 data has been updated. Many locations are in both but some are only in one set. Quite a few locations have shifted the measuring point from the town centre (often the Post Office) to the local aerodrome. It is not the case that the newer data has higher temperatures (perhaps due to Global warming) as there is much variation due to which years are chosen and indeed in many cases, the later temperatures are lower.
Yes, you can but it is not available from within CAMEL. If you go to the top of the first pull down location list the second entry is ‘user defined monthly’. Once selected, an Edit/Add button appears which will open a new form where you can enter and save the ASHRAE or other weather data.
If you go to the top of the first pull down location list the second entry is ‘user defined monthly’. Once selected, an Edit/Add button appears which will open a new form where you can copy the data from the existing location then change any entries you need to (say +0.5 for all CDB etc) then save the data with a modified name eg Sydney +0.5.
For example, let us assume that the North wall is facing 15° west of North i.e at 345° (entry on the Project Screen). The input data for that external wall could be entered as 0° or exposure N.
In the results, on the room load chart for that room, the wall should show exposure of 345° (0° plus 345°). [correspondingly E would be 75°, S 165° and W 255°].
The Leaving Coil temperature is limited by the minimum leaving coil temperature shown on the Project Tab. If that was set to 12° then you cannot have leaving coil temperatures less than 12°.
Shading Effectiveness is only used to calculate equivalent shading dimensions for use in the Section J glass calculator 2016 Version. As it can slow down the calculations significantly it should normally be left blank.
Windows
No. It is only the top 7 lines of the data that are used in the calculations and must therefore be completed. The lower 7 lines are simply an aid (based on selecting a glass number by right clicking on the glass number line) to obtaining this data.
If the Glass Number is entered or selected on line 8;
- and the ‘U Value for CAMEL’ is double clicked, it then replaces the U-Value on line 4
- and the ‘Shade Coeff. For CAMEL’ is double clicked, it the replaces the Shade Factor on line 5
- and the ‘Internal Shading’ on line 7 is entered as YES the Int Solar Atten Coeff on line 13 can be entered and will be used to multiply the shade coefficient (line 12) when it is moved up to line 5.
- and the Frame U Value Corr’n if entered will be applied to the U Value (line 11) to allow for the frame when it is moved up to line 4.
Shade Factor is simply the overall shade coefficient for the glass only, modified by any internal curtains or blinds. It is defined as the ratio of the Solar Heat Gain for the actual window glass, to Solar Heat Gain for reference glass (taken as 3mm clear glass). Since the SHGC for 3mm clear glass is 0.88 or 0.89 then the Shade Factor for glass is it’s SHGC divided by 0.88 (assuming no blinds or curtains).
Walls
CAMEL includes some 130 wall types and some 87 roof types. If your walls and roofs can be represented by these, then there is no need to enter the wall or roof types you are going to use on the External walls or roofs on the Walls tab. However, if you want walls or roofs of different construction or insulation values, then they need to be entered here and referenced on the external tab. Note the U-Value includes the inside and outside film coefficients.
AHU
Yes. If you set up a chilled water sub-circuit (or more) then various FCU can be connected to the entered sub-circuits and are still included in the chiller total.
VRF indoor units are entered as AHUs and each must be connected to a VRF outdoor unit circuit. The results then include the total load on each outdoor unit.
The default values for the room design conditions are set in the front screen, file menu > Project defaults, but remember those only apply when starting a new data set. If you wish to change the room design conditions in the current data, use the ‘show all’ mode for the AHU tab, change the first value then use down arrow and ‘=’ to rapidly set the others.
O/A can be entered in two places, either the AHU tab, (if a fixed L/S or % of Supply Air is used) OR the Zone & Rooms tab if L/s/person or/m2, air changes or fixed L/S for the room is required.
Zones and rooms
Yes. If you set up a chilled water sub-circuit (or more) then various FCU can be connected to the entered sub-circuits and are still included in the chiller total.
The Ceiling height is only used in CAMEL to calculate internal volumes for air change volumes, so the ceiling height should be the height of the occupied space (with air movement).
On the Zones and Rooms Screen, the Storage Mass can be entered directly by the user. As an alternative, it can be calculated by right clicking on the mouse symbol. However, the form which comes up will only have the data filled in (for walls, floors, roofs etc.) after the external and partitions tabs have been filled in. Therefore the calculation of storage mass needs to be done after the rest of the data is completed.
This is always difficult to calculate and is an estimate of the Ambient air entering the building other than through the A/C system. DA9 has a rule of thumb estimating method but remember this may be offset by the Outside Air introduced into the A/C system.
This allows for air extraction from the room (e.g. A fume cupboard or exhaust hood), provided that the exhaust volume does not exceed the Outside Air. This will also reduce the R/A exhausted at a Heat Exchanger which may adversely affect the efficiency of the Heat Exchanger.
External
There are 3 possible shading schemes allowed for each wall or roof. A shading may be entered on the surface (wall or roof). A similar but different shading scheme may be entered on each of the windows in that surface and thirdly, the possibility of shading from an adjacent building or structure.
Yes. A roof or external wall can have many different window types. Each extra window type is added by clicking the button “Add Window” which adds an additional column of window data for that wall. Note that each external wall or roof must have a window added before a second window is added to that surface.
HYENA [ SPRINK ] FAQ
The following questions relate to various program tabs (or screens) or general design and sketch.
Design and Sketch
Wherever you want to analyse. If you make it the mains, or the tank, then the pump becomes a booster pump and the program will calculate the required pump pressure increase if you select the third “calculate” option on the project screen. If you make the input point the pump then the pipe losses on the suction side of the pump must be separately calculated and added to it.
No – the program does no conversions – the units are selected on the project screen. However if you enter all your pipe lengths as mm e.g. 2400, 3600, etc while in fact the units of length are set to m, when the results are checked there will be huge pressure drops since 2400 becomes 2.4 km of pipe etc. This can be fixed simply be changing the units of length to mm on the project screen without the need to re-enter all the pipe lengths.
If a pipe will have flow in it when the chosen sprinklers are operating then it must be included in the network. If pipes definitely have no flow ( e.g. feeding non-operational sprinklers), then they need not be entered.
Some suggestions:-
- Size of job – 20 pipes or 2000 pipes
- Pipes and Nodes may use different sequences g. pipes 5000-6000 and Nodes 1-1000
- One node of each pipe may be pipe number g. Pipe 233 has at one end node 233
- Large pipes (less of them) – Large Numbers e.g. 100, 110, 120 etc.
- Results list pipes and nodes by ascending number – Input point may be 1 (first) or 9999 (last)
- Keep operating sprinklers together
- Sprinklers first! 1 – 20
- Auto Numbering – right clicking on similar pipes column
- A system that minimises mistakes
Different scenarios can be tried by checking some sprinklers and/or hydrants as operating in different runs or alternatively the lengths of some pipes may be changed to “move” the area of operation.
This version of the program allows the entry of hydrants directly with their required flow and minimum pressure. This is turned into an effective K factor for the most remote hydrant ; others are treated as “fixed discharges”. That is they are discharging the minimum flow unless the “hydrants Flow” just above the Node No. is set to variable in which case they are all treated as a K factor with those closer to the input point discharging more than the minimum.
Fixed discharges need only be used in special circumstances as with a fixed discharge the entered discharge occurs regardless of the available pressure which may be to low to ensure the required flow is actually discharged – something the user must always check. This can be useful in cases where large industrial ring mains are analysed with separate sub-sections treated as fixed discharges but the user must always check available pressures.
Prepare a drawing or sketch with:-
- Show Area of operation (operating sprinklers)
- Ignore pipes without flow
- Determine pipe diameters and mark on drawing
- Mark Input points and Pumps
- Mark Node Nos.
- Mark Pipe Nos.
- Elevation of all Nodes
- Any Fittings apart from elbows and tee’s
- Determine flow and k-factor for each operating sprinkler or nozzle
- Pipe Lengths (scale or dimension)
The “best” depends on the users assessment.
FIXED – A fixed pressure at an input point typically a tank OR if the required input pressure is being determined then a guess pressure (typically 1000 kPa) in which case only Pressure 1 is entered.
If the input pressure is not a constant, but a curve (e.g. if the input is a pump, the pressure will drop off as the flow increases), then the curve can be described in one of three ways:
LINEAR – signifies a pump or variable water supply pressure being entered as a series of (at least two) points on a curve of pressure vs flow. The program linearly interpolates between the entered points. For better accuracy the points should be closest in the vicinity of the operating point.
CURVE – signifies a pump or variable water supply pressure but in this case a series of coefficients are calculated from the entered values of flow and pressure for a polynomial fit to the points. All eight points must be entered. This may be a slightly more accurate method of describing a pump curve than the LINEAR method but remember that the curve will not necessarily pass through all points (least squares fit).
The polynomial takes the form:
p = a + bq + cq2 + dq3
where p is the pressure and q is the flow and
Q18 – signifies a variable water supply pressure where the pressure between each pair of entered points is proportional to the flow to the power 1.85. This is typically the data supplied by a water supply authority.
General
On the front screen – File menu > Project default the user can set the default locations, plant operating times, inside design conditions and various storage masses.
On Front screen Menu bar select Shadow [or button]. Now select the ‘Room’ and ‘Surface Number” required and the time and month or even animate it, so it steps through the months at a time of day OR steps through the hours of the day in one month.
Use the comments button on the project tab – Comments appear on the project details output. Alternatively, you can send the selected results to a word document that will allow you to add any comments wherever you like.
Primarily Australian and NZ and also PNG, Pacific Islands, China and a limited number of locations in South East Asia – see the pull down lists on the project screen. Australian and NZ locations are also shown on a map (button on the project screen). Other data (e.g. ASHRAE) can be entered and saved by selecting the second top entry (user defined monthly) in the locations list.
Input point
The “best” depends on the users assessment.
FIXED – A fixed pressure at an input point typically a tank OR if the required input pressure is being determined then a guess pressure (typically 1000 kPa) in which case only Pressure 1 is entered.
If the input pressure is not a constant, but a curve (e.g. if the input is a pump, the pressure will drop off as the flow increases), then the curve can be described in one of three ways:
LINEAR – signifies a pump or variable water supply pressure being entered as a series of (at least two) points on a curve of pressure vs flow. The program linearly interpolates between the entered points. For better accuracy the points should be closest in the vicinity of the operating point.
CURVE – signifies a pump or variable water supply pressure but in this case a series of coefficients are calculated from the entered values of flow and pressure for a polynomial fit to the points. All eight points must be entered. This may be a slightly more accurate method of describing a pump curve than the LINEAR method but remember that the curve will not necessarily pass through all points (least squares fit).
The polynomial takes the form:
p = a + bq + cq2 + dq3
where p is the pressure and q is the flow and
Q18 – signifies a variable water supply pressure where the pressure between each pair of entered points is proportional to the flow to the power 1.85. This is typically the data supplied by a water supply authority.
The Input point is entered as a FIXED pressure and this represents the minimum depth of water available at the tank exit (500mm water is 5kPa), the user can enter the loss coefficient of an abrupt exit from the tank. The pressure loss of this fitting is added to the pressure loss of the pipe from the input point (tank).
Grid general
- This is all the Grid types available but the number of range pipes may be varied in each type. You may be only have one, two or three main pipes as illustrated on the buttons. However, these
‘standard’ grids may be XPANDED so that each pipe is individually listed and may therefore be changed.
Those sprinklers operating in the grid may be selected on the operating sprinklers tab. In addition, more pipes and operating sprinklers may be added using the original ‘pipes’ and discharge’ screens provided these pipes and sprinkler numbers do not clash with the numbers in the grid.
Grid Ranges and Trees
This is simply the number of sprinklers on the range pipes.
The diagram on the right illustrates the dimensions and diagram changes when you click on a particular line.
Not usually as HYENA will include the standard T’s at the end of the range and trees. Remember that any fitting added by you will be added to each range or tree pipe!!
Simply leave the line blank and the program assumes that the sprinklers are screwed directly into the range and tree pipes.
If droppers are added they can either be a fixed length (ie following the slope of the range pipes) or putting the sprinklers at a fixed elevation. In this latter case the dropper length is calculating the vertical distance between the nominated elevation and the elevation of the range and tree pipes enforced on the elevation tab.
Grid Elevations
Just set the horizontal elevation of Row 1 and each subsequent row defaults to the previous one. Hence all will be horizontal.
Select the sloping option for the first row and enter the 3 heights and two dimensions to specify the range. By default this will then apply to all other rows.
Project
No – the program does no conversions – the units are selected on the project screen. However if you enter all your pipe lengths as mm e.g. 2400, 3600, etc while in fact the units of length are set to m, when the results are checked there will be huge pressure drops since 2400 becomes 2.4 km of pipe etc. This can be fixed simply be changing the units of length to mm on the project screen without the need to re-enter all the pipe lengths.
No, this data has NO affect on the calculations. It is simply a record of the design data used to calculate the flow for each of the discharging sprinklers.
In most systems (with only one input point) all check valves are open in normal operation and so they need not be operating. (The equivalent length for check valves assumes they are open). Only in special cases, such as multiple operating inputs, are operating check valves necessary. In this case the first pipe from each input point contains a check valve which would only operate if the pressure at the input point was so low that the flow was out of the network. In this case (with check valve operation “yes”) the check valve would operate and the program would remove the pipe containing the check valve from the calculation thus preventing flow out of the network.
Pipes
For most pipes it does not matter which end is A and which is B. It does not make any difference if the flow is from A to B or B to A. In the results for the pipes the nodes for each pipe are listed in the direction of flow. However whenever some specific fittings or devices are included in a pipe it is important that a node A and node B are in the direction of flow and hence pressure change from A to B. These specific fittings include Booster Pumps, Backflow Preventers, Operating check valves, pressure reduction devices OC, OF, OD, OP, PZ.
If you select the same pipe material as the default pipe material (at the top of the column) then it goes blank since blank on any pipe means that it takes the default material.
Left click on the “other fittings” column for that pipe then Right click and a list of the fittings available in the program for that pipe material will appear – User defined fittings are shown at the bottom of the form.
ASAM is steel pipe to AS1070 medium weight and that standard only goes to 150mm diameter. If you need 200 mm pipe you will have to select a different standard e.g. AS40 for schedule 40 ansi which has sizes up to 1050mm
To save selecting all the sprinklers on the pipes screen nodes – enter the sprinklers first on the discharges screen. Provided the sprinklers are continuously numbered e.g. 20, 21, 22, ….33 then they may be entered using the “+” button and set the default elevation, flow, K factor and pressure exponent. When these nodes are entered on pipes on the pipes screen they will automatically come up as “sprinkler” as each pipe line is completed.
If a pipe will have flow in it when the chosen sprinklers are operating then it must be included in the network. If pipes definitely have no flow ( e.g. feeding non-operational sprinklers), then they need not be entered.
Some suggestions:-
- Size of job – 20 pipes or 2000 pipes
- Pipes and Nodes may use different sequences g. pipes 5000-6000 and Nodes 1-1000
- One node of each pipe may be pipe number g. Pipe 233 has at one end node 233
- Large pipes (less of them) – Large Numbers e.g. 100, 110, 120 etc.
- Results list pipes and nodes by ascending number – Input point may be 1 (first) or 9999 (last)
- Keep operating sprinklers together
- Sprinklers first! 1 – 20
- Auto Numbering – right clicking on similar pipes column
- A system that minimises mistakes
Yes providing that you use the correct 2 character identifier separated by spaces e.g. GV for Gate Valve.
Discharges
Sprinklers and spray nozzles are designed to produce certain spray characteristics. It is generally accepted in the fire protection industry to use the discharge coefficient (or k factor) when determining the flow through a sprinkler or nozzle. i.e. Q = k x Pn where the pressure exponent n is taken as 0.5. Highly engineered sprays, as opposed to standard deflection type sprinklers, often contain complex internal and external geometries to form the distinctive spray patterns. In order to account for the different flow characteristic of these types of discharges, the pressure exponent can be considered as an input variable rather than a constant. See help or F1 for typical examples.
No – Only if you want the program to check that the max pressure is not exceeded – in which case a warning message is included.
Provided the sprinklers are continuously numbered e.g. 20, 21, 22, ….33 then they may be entered using the “+” button and set the default elevation, flow, K factor and pressure exponent. When these nodes are entered on pipes on the pipes screen they will automatically come up as “sprinkler” as each pipe line is completed.
Reference Nodes
Measurement Node is a node where the measurements are to be taken when testing/certifying the system. If entered an extra line with the flow and pressure at this node is listed in the Summary Results.
It must be a Reference node and must have two and only two pipes connected.
Booster BFP
An input point with a pump curve is taking the pump as the input point. Any pipes and therefore pressure losses on the suction side of the pump must then be separately calculated and added to find the total pump requirement. A booster pump is a pump further down the network such that the pipes on the suction side of the pump are included. Note that input points are at nodes where booster pumps occur “in” pipes. This is often best done by having a short length of pipe with the pump and say two gate valves included.
Back flow preventers (BFP) are entered on the “Booster BFP” tab and up to 8 pairs of flow/pressure points are added from the manufacturers data.
Grid Main Pipes
There will always be one less main pipe than the number of rows!
While many grids have the same main pipe diameter from one end to the other, in the case of trees it often occurs that as the main pipe approaches the remote end, it’s diameter drops. This can be done by listing the number of MPL of each diameter starting from the bottom up.
Usually NO. HYENA will include all the fittings (principally Tees) which are needed. Also remember that any fitting added to a main pipe will be inserted into all those main pipes.
In a grid, the range pipes are often close to the roof running parallel to the beams. The main pipes run across and below the beams. The short lengths of vertical pipe connecting the main pipes to each range pipe are known in HYENA grids as ‘Rising Main Pipes’.
You do not enter the length of the RMP’s. In the RMP data you enter, the elevation of each pipe (measure from the datum). Later on the elevation tab, the elevation of the range of the tree pipes is entered and the length of the RMP is taken as the difference in elevation of these pipes.
Grid Op Sprinklers
Just click and drag the cursor from the top left corner to the bottom right corner of the rectangular area containing the operating sprinklers. Having chosen the actual operating sprinklers the min flow and K factor (and pressure exponent if not the usual 0.5) need to be entered in the floating form. Should an extra sprinklers be operating then select these and add a second line of data on the floating form. The colour of the sprinkler X on the diagram corresponds to the coloured block at each end of the data lines.
If it is required that the program determines the most remote (unfavourable) area of operation for the selected sprinklers, the area of the GRID to be considered for this is entered on the Remote line on the floating form, by windowing the area required.
The program will then calculate the hydraulically most remote region for the nominated operating (discharging) sprinkler heads by moving the operating sprinklers around the GRID over the remote area specified.
The most remote region is defined as the sprinkler locations that produces the least flow from any of the operating sprinklers.
Grid Numbering
The values entered in the first column allows the user to change the numbering on large grids. Opposite each of these are the start and end pipe and node numbers for each. This helps the user avoid clashing pipe and node numbers. Note that the node and pipe numbers can also be seen in the graphic display of the grid activated by selecting the “view Grid” button.
