Calculator Inputs and Outputs
Inputs
- Flow rate (L/min) — example: 90
- Total dynamic head (m) — example: 24
- Fluid density (kg/m³) — example: 998
- Overall pump efficiency (%) — example: 72
Results
- Required input power (kW)
- Hydraulic output power (kW)
- Required input power (hp)
Formula used
Hydraulic power = density × gravitational acceleration × flow in m³/s × head; input power = hydraulic power ÷ efficiency.
