Pump efficiency
How to calculate pump efficiency by CFD?

I have one method. Kindly let me know its correctness. Calculate discharge total pressure (DTP), flow rate (Q) and impeller torque (T) by CFD. w is rotational speed of pump.

Efficiency = (DTP*Q) / (T*w)

This ignores the frictional losses and bearing losses.
