Understanding Water Horsepower

Water horsepower (WHP) is a unit of power that measures the power required to move a certain amount of water against a given head. It is commonly used in pump systems to determine the required pump size.

Formula

The formula to calculate water horsepower is:

WHP = (Q × H) / 3960

Where:

  • Q is the flow rate in gallons per minute (GPM).
  • H is the total head in feet (ft).

Example

If a pump has a flow rate of 100 GPM and a total head of 150 ft, the water horsepower required would be:

WHP = (100 × 150) / 3960 = 3.77 WHP
