Pump Head and Power Calculator vs Pump Power & 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 Head and Power Calculator
Calculate the shaft power required to drive a centrifugal pump given flow rate, static head, friction losses, and pump efficiency. Use this when sizing pumps for piping systems.
- Answers
- Required Pump Power (W)
- Inputs
- Flow Rate, Static Head, Friction Loss, Fluid Density, Pump Efficiency
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
