Running a Hydrant Curve Analysis

00:04

A fire hydrant rating curve shows the relationship between

00:07

residual pressure and the available flow for any hydrant.

00:11

Hydrant curves are often required by

00:13

fire departments responsible for ensuring that a

00:16

specific hydrant can adequately control a

00:18

potential fire demand and maintain minimum pressure

00:22

to begin.

00:23

Double click the desired project dot APR X file to open

00:27

Agis Pro.

00:29

Once the project starts,

00:30

click the info water pro tab to open the info water pro ribbon

00:34

in the project panel, click initialize

00:38

to set up and run a hydrant curve on the info water pro ribbon

00:42

in the analysis panel. Click run

00:45

in the run manager, click the hydrant curve tab

00:49

to set the start time for this simulation.

00:51

Pick select time and then in the pop-up click and

00:54

drag the slider to set the time to 10 hours.

00:58

Click. OK.

01:00

In the target junction ID field enter J 101 198

01:03

as the identifier of the hydrant to be tested.

01:07

You can also use the browse icon beside the

01:09

field to select the junction directly from the map.

01:14

Set the normal hydrant flow to the hydrant's firef flow demand.

01:18

Click run

01:21

the hydrant curve graph opens automatically in the report manager.

01:25

If you are prompted to switch to the most recent output data. Click yes,

01:30

view the graph.

01:32

Any brakes in the curve are caused by a

01:34

change in operation at the specified flow rate.

01:38

When you are finished reviewing the curve, close the report manager.
