Calculate the required hydraulic horsepower for a pump based on flow rate, pressure, and efficiency. Essential for motor selection in fluid systems.
It is the power actually transferred to the fluid. Brake Horsepower (which this calculates) includes the inefficiency of the pump.
Check the manufacturer's pump curve. Standard centrifugal pumps operate between 50-85% efficiency depending on the operating point.
HP = GPM * PSI / (1714 * Eff)
