I have a specified pipe diameter, and a specified supply pressure. I would like to know how to calculate either volume in ft/sec or flow rate in gpm. I know how to get from volume in ft/sec to flow rate in gpm, but not how to get from psi to max flow rate in gpm.
I'm trying to find a standard flow rate in gpm for PVC pipe on a city line at a give psi. I can calculate gpm from velocity, and can find pressure drop, but am unable to find a table or equation for this calculation
