How do you calculate hydraulic horsepower?

Hydraulic horsepower shows how much power a hydraulic system delivers based on how much pressure and flow it has.

Use this formula:

HP = (PSI X GPM) ÷ 1714

• PSI = system pressure
• GPM = flow rate
• 1714 = a constant that converts the numbers into horsepower

Example

If the hydraulic system has a pressure of 1500 PSI and a flow rate of 25 GPM:

HP = (1500 X 25) ÷ 1714

HP = 21.88 horsepower

So, the hydraulic system produces about 21.88 HP (rounded to the nearest hundredth).
