Turbopump Power Estimator
Estimate hydraulic and shaft power for a pump from mass flow, pressure rise, density, and efficiency.
Shaft power
294.12 kW
394.4 hp turbine-side input
Hydraulic power
200.00 kW
flow times 8.00 MPa pressure rise
Volumetric flow
25.00 L/s
25.00 kg/s at 1,000 kg/m3
Pump energy rise
The pump converts shaft work into hydraulic power by pushing a measured volumetric flow through the required pressure rise.

Pump power chain
Pshaft = delta-p Q / eta
Volumetric flow
25.00 L/s from 1,000 kg/m3
Power split
200.00 kW hydraulic
94.12 kW lost at 68% efficiency
Shaft drive
