1.	A pump on the ground floor of a building can pump up water to fill a tank of volume 30 m^3in 15 min. If the tank is 40 m above the ground, how much electric power is consumed by the pump. The efficiency of the pump is 30%
Answer» Answer :`30% "of POWER"=W/t=(mgh)/t=(vpgh)/t` `(30)/(100)xxp=(vpgh)/t` `p=43.6KW`
