Pump Power & Efficiency Calculator vs Pump Power and Efficiency Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Pump Power & Efficiency Calculator
Find the shaft power (kW) needed to drive a pump given flow rate, head, fluid density, and combined pump-motor efficiency. Use it when selecting motors or verifying energy consumption for water supply, HVAC, or process systems.
- Answers
- Motor Power Required (kW)
- Inputs
- Flow Rate, Total Dynamic Head, Fluid Density, Pump Efficiency, Motor Efficiency
Pump Power and Efficiency Calculator
Calculates the shaft power a pump must deliver to move fluid against a given head, accounting for pump efficiency. Used when selecting pumps for water supply, irrigation, HVAC, and industrial process systems.
- Answers
- Required Power (kW)
- Inputs
- Flow Rate, Total Head, Fluid Density, Pump Efficiency
