An electric motor with an efficiency of 78% drives water pump. What input power is required of the motor (in kW) to pump 22250 gals of the water from the lake to a storage tank 65 feet above the lake surface in 4 hours?
Attempt :
i know that efficiency = output/input
but i don't understand, how to calculate the output through this data
