A system head curve analysis shows the relationship between system head
00:08
and flow capacity for a pump at different time ranges.
00:14
This relationship represents the variation in total dynamic head against the
00:18
pumps required to operate under various flow conditions throughout the network.
00:23
To begin. Double click the desired project dot APR X file to open
00:28
Agis Pro.
00:31
Once the project starts,
00:32
click the info water pro tab to open the info water pro ribbon
00:37
in the project panel, click initialize,
00:41
you can perform a system head curve analysis from the run manager
00:46
on the info water pro ribbon
00:47
in the analysis panel, click run
00:52
in the run manager, click the system curve tab.
00:56
First you choose the pump that you want to evaluate by either entering
00:60
the target pump id or by clicking browse to graphically select the target
01:04
for this exercise in the target pump ID field. Enter P 140.
01:11
Next set the curve type two exponential as this
01:14
system curve will be generated by a single simulation.
01:18
Then under report data points,
01:21
you enter the number of data points or the number of
01:23
flow increments at which the system curve will be generated.
01:26
And data will be reported
01:28
for this exercise.
01:30
Enable only one of the system curve at zero hour options but do not select any times.
01:36
If you enable all three system curve time periods
01:39
to evaluate a wide range of operating conditions,
01:41
you could set the three available times to
01:44
represent times of low average and peak demand
01:48
click run to run the simulation.
01:51
The report manager appears with the system curve for pump P 140
01:56
system head curves are useful for designing pumps.
01:60
You can use system head curves along with
02:02
pump efficiency curves to assist with efficient pump design
02:06
when you are finished, click hide to close the report manager.
