Pump Efficiency Calculator
Posted by Dinesh onUse this simple hydraulics and waterworks calculator to calculate pump efficiency. Pump performance is measured in terms of the capacity that a pump can discharge against a given head and at a given efficiency.
Pump Efficiency Calculator
Formula:
Ep = (γ × Q × Ht) / Pi : [for SI units]
Ep = (γ × Q × Ht) / (bhp × 550) : [for U.S. customary units]
- γ - specific weight of water
- Q - Capacity
- Ht - total dynamic head
- Pi - power input
- bhp - brake horsepower
- Ep - pump efficiency, dimensionless
