A motor pump fills a tank of volume `30m^(3)` at a height `40m` with water in `30 min`. If efficiency of motor pump is `40%`. Find the rate at which electrical energy is consumed?

A pump on the ground floor of a building can pump of water to fill a tank of volume 30 ms^(3) in 15 min . If the tank is 40m above the ground and the efficiency of the pump is 30 % , how much electric power is consumed by the pump? ("Take" g = 10 ms^(2))
