Question

What is the output rating of generator for a given data?

torque and speed of turbine to which it is to be connected are

17 Nm and 375 rpm at a pressure of 7 bar.

Answer 1

If the input torque and speed are 17 Nm and 375 RPM, the input power is given by kW = Torque X RPM / 9550 or 17 X 357 / 9550 = .667 kW. The output power would be input power X efficiency. A 3-phase generator that size might have an efficiency of 0.85 if it were to be designed for maxmum efficiency, but the selected voltage and frequency would put constraints on the design.
