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.

Step-by-step:

A System Head Curve Analysis shows the relationship between system head and flow capacity for a pump at different time ranges. This relationship represents the variation in total dynamic head against the pumps required to operate under various flow conditions throughout the network.

  1. Open the appropriate .aprx file in ArcGIS Pro.
  2. From the ribbon, InfoWater Pro tab, Project panel, click Initialize.
  3. On the ribbon, InfoWater Pro tab, Analysis panel, click Run.
    The ribbon, InfoWater Pro tab, with the Run tool highlighted in the Analysis panel
  1. In the Run Manager, click the System Curve tab.

Choose the pump that you want to evaluate by either entering the Target Pump ID or by clicking Browse to graphically select the target.

  1. In the Target Pump ID field, enter P-140.
  2. Set the Curve Type to Exponential, as this system curve will be generated by a single simulation.

Under Report Data Points, enter the number of data points or the number of flow increments at which the system curve will be generated and data will be reported.

  1. Enable only one of the System Curve @ 00:00 hr options.
  2. Do not select any times.
    The Run Manager, System Curve tab, with the settings configured to create a system curve for one time period

Note: If you enable all three System Curve time periods to evaluate a wide range of operating conditions, you could set the three available times to represent times of low, average, and peak demand.

  1. Click Run to run the simulation.

The Report Manager appears with the System Curve for Pump P-140:

System head curves are useful for designing pumps. You can use system head curves along with pump efficiency curves to assist with efficient pump design.

  1. Click Hide to close the Report Manager.
