The power of a motor pump is 2 Kw . How much water per minute the pump can raise to a height of 10 m . Take g = 10 m s ^-2

Dear student
Given that , power of the pump is = 2kW  or 2000W
Time (t)= 1 min = 60sec
Height (h) = 10m
We have the relation $Power P=\frac{dW}{dt}$
Work done, dW = mgh = m ×10×10 =100m
Now 2000W =$\frac{100m}{60sec}$
Therefore, ,mass m = 1200kg
So, the pump can raise 1200kg of water in one minute.
