power=workdone/time taken
according to question;
power= 5kw=5000watt
height=20 m
time= 1 minute =60 sec
g=10m/s^2
power=mgh/time taken
5000=m x 10 x 20/60
m=5000 x 60/200
m=1500 kg
density=mass/volume
volume=mass/density
volume of water=1500/1000=1.5 m^3
1m^3 =1000 litres
1.5 m^3 =1.5 x 1000= 1500 litres
therefore mass of water that can be lifted per minute by the pump is 1500 kg
OR
amount of wate that can be lifted by the pump per minute is 1500 litres
