You can use a steady state analysis as the
00:05
starting point for creating an extended period simulation.
00:10
In this example,
00:11
a 24 hour time period and boundary conditions such as pump status
00:16
and tank levels were already configured for a steady state analysis.
00:21
However,
00:22
variations in these conditions were not
00:24
specified for an extended period simulation.
00:28
In this exercise,
00:29
you will define controls for the pump operations in preparation for an E P S
00:36
to begin. Double click the desired project dot APR X file to open Argi
00:41
Pro.
00:42
Once the project starts,
00:44
click the info water pro tab to open the info water pro ribbon
00:49
in the project panel, click initialize
00:53
zoom to the treatment plant
00:56
in the contents pane right,
00:58
click the pump layer and select label to enable labeling for the pumps
01:03
on the info water pro ribbon in the edit panel, click the select icon
01:07
and then select pump P 120 in the map
01:12
in the model explorer on the attribute tab, click tools and select control
01:18
in the pump control dialog box set. The following
01:22
set the status type to open
01:25
for the method, choose pressure slash head and enter T 5004 as the node id.
01:33
If you did not know the id of the control tank,
01:35
you can click the arrow beside the ID field to be able to graphically select the tank
01:41
set, the level value two below with a value of 114
01:48
click insert and note the new row added to the control data section.
01:53
This signifies that the pump will turn on when the
01:55
water level at tank T 5004 drops below 114 ft.
02:02
Now set the status type to closed and the level value to above with a value of 127.
02:12
Click insert,
02:13
the pump will turn off when the level at tank T 5004 rises above 127 ft.
02:20
Click create.
02:23
Now you will create controls for two other pumps in the system.
02:27
Select pump P 100
02:29
open the control dialog box. Again from the model explorer attribute tab
02:34
tools
02:35
control.
02:38
You want this pump to turn on when the water level in tank T 5004 drops below 109 ft
02:45
and turn off when it rises above 118 ft
02:51
fill in the open and closed settings accordingly.
02:55
Note that this pump operates in tandem with pump P 120.
02:59
Pump P 120 comes on first when the tank level drops to 114 ft.
03:05
Pump P 100 will turn on only if pump P 120 cannot prevent
03:10
the tank level from dropping an additional five ft to 109 ft.
03:15
Click. Create
03:19
select pump P 140
03:21
open the control dialog box.
03:26
Create the settings so that this pump will turn on when
03:29
the water level in tank t 5000 drops below 77 ft
03:33
and turn off when it rises above 95 ft,
03:40
you have now set up control settings for three pumps
03:43
with specific variations in conditions for an extended period simulation.

you have now set up control settings for three pumps
03:43
with specific variations in conditions for an extended period simulation.
You can use a steady state analysis as the starting point for creating an extended period simulation. In this example, a 24-hour time period and boundary conditions, such as pump status and tank levels, were already configured for a steady state analysis. However, variations in these conditions were not specified for an extended period simulation. In this exercise, you will define controls for the pump operations in preparation for an EPS.
Notice the new row added to Control Data. This signifies that the pump will turn on when the water level at tank T5004 drops below 114 feet.
This second row signifies that the pump will turn off when the level at tank T5004 rises above 127 feet.
Note that this pump operates in tandem with pump P-120. Pump P-120 comes on first when the tank level drops to 114 feet. Pump P-100 will turn on only if pump P-120 cannot prevent the tank level from dropping an additional 5 feet to 109 feet.
Pump P-140 will now turn on when the water level in tank T5000 drops below 77 feet and turn off when it rises above 95 feet.
The control settings are now configured for three pumps with specific variations in conditions for an extended period simulation.
