given volume of water = 1500 litres
1m^3=1000 litres
then 1500 litres =1500/1000=1.5m^3
density = mass /volume
mass=density x volume
mass of water = 1000x 1.5=1500 kg
work done =mgh=1500x10x21=315000 joule
power=workdone/time taken
power = 315000/60=5250 watt
1 horse power= 746 watt
then 5250watt = 5250/746=7.04 watt approximately
