Pump Efficiency for Pumping Station - Accurate?

Hi, I am Narendra Shah, a student. I am doing a project on the water supply scheme of Karjat town. I wanted to calculate the efficiency of pumping station of raw water and water treatment plant. I have given the details above. Please help me.


Pumping Station

Head= 42 m

Flow = 86 litres/s

Pumps = 80 HP (three pumps of 80 HP each)

Transformer: 200 kVA

I have read that Pump Efficiency  = Power water/Power input

                                                = (Head)*(Flow)*(9.81)/Power Input/Power factor


Please let me know if I am on the right path. If yes, please tell me how to calculate power factor.


Thank You

Narendra Shah
