Apump is driven by electric motor with an efficiency of 0.87and with theoretical output of 22.2 gpm actually produces only 19.1 gpm. the pressure at the pump outlet is 2850 psi. if the pump has a mechanical efficiency of 0.97, what input horsepower is required to drive the pump? the electric motor is being operated for 15 hours a day and 235 day a year, how much electricity cost at $0.77 per kilowatt hour. how much operating cost is wasted yearly?
