Understanding Horsepower and Water Horsepower: Efficiency

Understanding Horsepower and Water Horsepower: Efficiency

ter horsepower can be determined if the flow rate of the water and the force (pressure) required to produce that flow are known. The following formula can be used to calculate water horsepower (WHP). WHP = HQ / 3960 Where H is the change in pressure measured in height of water in feet and Q is the water flow rate in gallons per minute.
