Understanding Horsepower and Water Horsepower Efficiency

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 This equation was derived knowing that one horse-power is equal to 550 ft-lb/s For example if an irrigation pump located at ground
