1.	An electric pump on the ground floor of a building taken 15 minutes to fill a tank of volume 30ms^(3) with water. If the tank is 40m above the ground and the efficiency of pump is 30% find the electira power consumed by the pump in filling the tank. [density of water = 10^(3) kg//m^(3)
Answer» SOLUTION :mass of the water to be filled = `("VOLUME of the tank") xx "density of water m = 30 xx 10^(3)kg` h = 40m, `t = 15 xx 60 = 900sec`. EFFICIENCY `ETA = 30%` Inputpower `P_(1) = (100)/(eta) xx (mgh)/(t)` `=(100xx30xx10^(3)xx9.8xx40)/(30xx900)=43.56KW`
