An electric pump on the ground floor of a building takes $$10$$ minutes to fill a tank of volume $$30$$ $$m3$$ with water. If the tank is $$60$$ m above the ground and the efficiency of the pump is $$60$$%, how much electric power is consumed by the pump in filling the tank?

Question

An electric pump on the ground floor of a building takes $$10$$ minutes to fill a tank of volume $$30$$ $$m3$$ with water. If the tank is $$60$$ m above the ground and the efficiency of the pump is $$60$$%, how much electric power is consumed by the pump in filling the tank?

Infinity Learn · Accepted Answer

Mass of water delivered by the pump to the tank.$$m=30$$×$$1000/600$$ $$kg/$$$$sec$$$$=50$$ $$Kg/$$$$sec$$∴ Power out put of the pump $$=$$ m.g.$$h=50$$×$$10$$×$$60W=30KW$$∴Power $$input=Power$$ $$outputEfficiency=300.6KW=50KW$$

An electric pump on the ground floor of a building takes 10 minutes to fill a tank of volume 30 $m^{3}$ with water. If the tank is 60 m above the ground and the efficiency of the pump is 60%, how much electric power is consumed by the pump in filling the tank?
