Calculating Flowrate Using Pressure
Calculating Flowrate Using Pressure
(OP)
Is there a formula to calculate flowrate (gallons per minute) for a 6 inch diameter chilled water pipe if I only have 2 values for pressure - 45 psi and 75 psi. Thanks.

You also need to adjust the pressure difference for any changes in height because you need the pressure drop due to friction only.
This was discussed recently and I posted the formulas and procedures there. See thread378-235298: water flow rate @ gauge pressure
