>>11361531>A pump which raises 120L of water per minute from a well 8.5m deep, is driven by a 250v DC motor. Assuming that the efficiency of the pump is 72% and that of the motor is 78%, calculate the current drawn from the supply by the motor. I can find the total Work done in Newton Meters, which comes to 10,006.2Nm, and then get the Power by dividing that by 60(seconds), to get 166.77watts, which I think is the pump output.
It's just needing to find out how much power the Motor inputs instead, for getting the current
