Calculation Formula

Water Horsepower (WHP) = (Q × P) / 3960

Where:
Q = Flow Rate (GPM)
P = Pressure (PSI)
3960 = Conversion factor ( Gallons per minute per PSI to horsepower)

Result

Water Horsepower (WHP): 0.00

What is Water Horsepower?

Water horsepower (WHP) is a unit of power used to measure the power required to move water through a system. It's commonly used in plumbing, irrigation systems, and water pumps.

How to Use the Calculator

  1. Enter the flow rate in gallons per minute (GPM)
  2. Enter the pressure in pounds per square inch (PSI)
  3. Click the "Calculate" button to compute the water horsepower

Applications

This calculator is useful for:

  • Designing irrigation systems
  • Selecting appropriate water pumps
  • Estimating energy requirements for water systems

Example Calculation

If you have an irrigation system with a flow rate of 100 GPM and a pressure of 50 PSI, the water horsepower would be:

(100 GPM × 50 PSI) / 3960 = 1.27 WHP
