WS pro allows a selection of hydrants to be tested against preset criteria.
00:10
A firef flow group and a version controlled firef flow object
00:14
are both required to store the hydrant parameters and testing constraints.
00:19
This is a way of testing hydrants to ensure they
00:21
can maintain both flow and pressure during fire emergencies.
00:26
Using the new nodes window, open the hydrants tab at the bottom of the window,
00:33
select all the hydrants and create a selection list group
00:37
to do so. Click the first row, then scroll to the bottom of the table
00:41
press and hold shift and click the last row.
00:45
Then in the model group window,
00:47
create the selection list group by right clicking Bridgetown firef flow,
00:50
then click new selection list group,
00:54
create the hydrant selection list by right clicking the
00:57
selection list group and selecting new selection list.
01:02
In the pop-up name, the new selection list hydrants
01:07
in the model group window, right?
01:08
Click Bridgetown firef flow, then click new firef flow group.
01:13
In this example,
01:14
the default name is selected but you can enter a custom name if you prefer.
01:19
Then
01:20
right,
01:20
click the new firef flow group and click new firef
01:23
flow and either accept the default name or type one in
01:27
double click. The new firef flow object to open the firef flow data dialogue.
01:34
In the hydrant testing constraints section
01:37
set the minimum flow to 15,
01:39
set the maximum flow to 20
01:42
adjust the minimum residual pressure to 15,
01:46
set the zone minimum residual pressure to 10.
01:50
Also set the network minimum residual pressure to 10.
01:54
Make sure keep local demand is enabled
01:58
based on the values you entered.
01:59
You will test one hydrant to see if it
02:01
can provide between five and 20 liters per second.
02:04
In the event of a fire at a nearby building,
02:07
you will also test if the hydrant itself can
02:09
maintain a minimum residual pressure of 15 m.
02:12
And if the immediate demand zone around the hydrant and
02:14
entire network can maintain at least 10 m of pressure
02:19
in the hydrant parameters group set the diameter to
02:25
Then in the hydrant valve parameters group set the valve diameter to 50
02:30
the valve curve to plug
02:31
and the loss coefficient to 1.5,
02:36
close the dialogue and then in the notification to save the changes. Click yes.
02:43
Now create a new run
02:45
right, click run group and select new run
02:49
in the schedule. Hydraulic run dialogue, enter hydrant testing in the title field,
02:54
check the box next to experimental
02:58
click and drag network control and demand diagram
03:01
to their respective areas in the dialogue.
03:05
In the run type group box, expand the dropdown and select firef flow.
03:10
The firefly options dialogue opens
03:13
enable hydrant testing which opens additional options,
03:18
click and drag the firef flow object and the selection list
03:21
of hydrants you created earlier into the respective areas of the dialogue
03:28
set the hydrant testing time to May 2nd 2022 at 10 o'clock
03:34
in the options group box check the boxes next to calculate pressure at min
03:39
and max firef flow,
03:40
calculate open hydrant flow
03:42
and calculate hydrant curve.
03:45
Click. Ok.
03:47
Then in the schedule, hydraulic run dialogue, click save and then run
03:53
instead of opening the run results in the GEO plan, right? Click it and select open as
03:59
in the select results, dialogue pick hydrant testing report then click. OK.
04:05
A grid opens showing how each hydran performed in the simulation.
04:09
Note that in the hydrant testing result column,
04:12
some of the hydrants have passed the set criteria and some have not.
04:16
This would indicate that if the set criteria were used to judge the compliance
04:20
of the network to provide the required firef flow under the specified conditions,
04:24
the hydrants that have failed would not be deemed compliant.

After performing a fire flow run:
Based on the values you entered, you will test one hydrant to see if it can provide between 5 and 20 liters per second in the event of a fire at a nearby building. You will also test if the hydrant itself can maintain a minimum residual pressure of 15 meters, and if the immediate demand zone around the hydrant and entire network can maintain at least 10 meters of pressure.
