Enter values and click "Calculate Power" to see results.

How to Use

Enter the flow rate, total head, pump efficiency, water density, and electricity rate. The calculator will determine the hydraulic power, shaft power, motor power, daily energy consumption, and monthly operating costs.

Hydraulic Power: Ph = (Q × H × ρ × g) / 1000
Shaft Power: Ps = Ph / η
Where:
Q = Flow rate (m³/s)
H = Total head (m)
ρ = Water density (kg/m³)
g = Gravitational acceleration (9.81 m/s²)
η = Pump efficiency (decimal)
