Calculate the brake horsepower (BHP) required for your pump with our easy-to-use tool. Ideal for fluid system design, our calculator uses flow rate, total head, specific gravity, and efficiency to give precise results. Optimize your pump selection today!
Formula:
The formula to calculate pump brake horsepower (BHP) is:
BHP = (Q × H × SG) / (3960 × Eff)
- BHP: Brake Horsepower (HP)
- Q: Flow Rate (Gallons per Minute, GPM)
- H: Total Dynamic Head (feet of fluid)
- SG: Specific Gravity (dimensionless, 1 for water)
- Eff: Pump Efficiency (as a decimal, e.g., 0.75 for 75%)
- 3960: A conversion constant for the given units.
