Hydraulic Flow to Horsepower Formula
The following formula is used to calculate the hydraulic horsepower for a given flow rate and pressure.
HP = (Q * P) / 1714
Variables:
- HP is the hydraulic horsepower
- Q is the flow rate in gallons per minute (GPM)
- P is the pressure in pounds per square inch (PSI)
To calculate the hydraulic horsepower, multiply the flow rate by the pressure and then divide the result by 1714.

What is Hydraulic Flow to Horsepower?
Hydraulic flow to horsepower is a measure of the power output of a hydraulic system. It is calculated based on the flow rate of the hydraulic fluid and the pressure at which it is delivered. This measure is crucial for determining the efficiency and capability of hydraulic machinery and systems. Hydraulic horsepower is commonly used in applications such as hydraulic pumps, motors, and other hydraulic equipment to ensure they are operating within their designed specifications.
How to Calculate Hydraulic Flow to Horsepower?
The following steps outline how to calculate the hydraulic horsepower.
- First, determine the flow rate (Q) in gallons per minute (GPM).
- Next, determine the pressure (P) in pounds per square inch (PSI).
- Finally, calculate the hydraulic horsepower using the formula HP = (Q * P) / 1714.
- After inserting the values and calculating the result, check your answer with the calculator above.
