Pipe Flow Calculations Forum

I need help sizing a 3way control valve on a air handler.
The infomation I have is:

139.7 GPM
PD 10FT

I assume that i need to convert the 10FT to PSI to find the CV rating.

Thanks

You can use gas control valve calculator and also find more information on theory page for gas control valves

The valve will be controlling hot water not gas.
