Water pumping duty
Estimate hydraulic, shaft and electrical power from required flow and total dynamic head.
Enable JavaScript for live calculations. Read the method and default example below.
Method and assumptions
- Clean water density assumed 1000 kg/m³; gravity 9.81 m/s².
- Head must include static lift and pipe / fitting losses.
Before using the result
- Match pump curves and check NPSH, water quality and starting demand. No pump or motor size is selected.
