Formula for Horsepower to Water Horsepower Conversion
The relationship between input Horsepower (HP) and Water Horsepower (WHP) is governed by the pump's efficiency (η), which accounts for energy losses within the pump. Water Horsepower represents the actual power imparted to the fluid.
WHP = HP × η
- WHP = Water Horsepower (power transferred to the fluid)
- HP = Input Horsepower (mechanical power supplied to the pump)
- η = Pump Efficiency (expressed as a decimal, e.g., 0.75 for 75%)
