February 15, 2008, 01:19	Pump efficiency	#1
john Guest Posts: n/a	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 = (DTPQ) / (Tw) This ignores the frictional losses and bearing losses. Thanks
