I need technical assistance for the attached cooling water model
KSP-Cooling Water System.wtg
Process Brief: The cold water from the elevated tank (actually a cooling tower) is pumped (fixed speed pump) through heat exchanger (chiller) and back to the tank. There are 7 cooling towers. 7 pumps and multiple heat exchangers all connected through common header arrangement. The model is attached. Now the task is to evaluate the head developed by the pump for this process.
Please provide your inputs for following:
Thanks

This model require wtg,sqlite to open! can you provide it??
There is an error while uploading the sqlite file, it says contact admin
Did you try to upload using link provided earlier? Sharing Hydraulic Model Files
Or you could directly upload here in your reply if the model files are not confidential or you can hover over name and send a private message with model files.

Hello Pratik,
In your pump definition, you have entered a design point where the flow is 14300 gpm and the head is 35 meters. Since your pump flows are all right around 14300 gpm, this is the reason that the pump head is around 35 meters.
If you are saying that the pump head needs to be lower, you would need to adjust the pump definition. If the pump definition is accurate, the head added by the pump is accurate as well.

I tried udpating the pump definition, by decreasing the had to 22 m. But then the error i receive is that the FCV's cannot achive the desired flow of 14300 gpm and also the pump flow drops below 11,000 gpm (less than the design requirement of 14300 pm)
