How to convert GPM to HP?
- Changing. Fluid Pressure – P. Fluid Flow Rate – Q. Fluid Power in Horsepower – HP.
- Word formula with units. (PSI) = force (pounds) / area (square inches) GPM = flow (gallons) / unit of time (minutes) horsepower = pressure (PSIG) × flow (GPM) / 1714.
- Simplified formula. P = F/A. Q = V/T. HP = PQ / 1714.
