Given, power of pump = 2kW =2000W
Time (t)= 60sec
Height (h) = 10m
g = 10m/s2
As you know, power =work done per unit time.
Work done = mgh = m ×10×10 =100m
Therefore, 2000W = 100m/60s
Therefore, m = 1200kg
So, the pump can raise 1200kg of water in one minute.

Work/Time = Power
mgh / t = P
m/t = P / (gh)
= (2000 Watt) / (10 m/s² × 10 m)
= 200 kg/s
It pumps 200 kg of water in 1 second
In 1 minute it’ll pump 200 kg × 60 = 12000 kg of water
∴ It raises 12 tonnes (12000 kg) of water per minute
mgh / t = P
m/t = P / (gh)
= (2000 Watt) / (10 m/s² × 10 m)
= 200 kg/s
It pumps 200 kg of water in 1 second
In 1 minute it’ll pump 200 kg × 60 = 12000 kg of water
∴ It raises 12 tonnes (12000 kg) of water per minute
