the power of motor pump is 2kW. how much water per minute the pump can raise to a height of 10m? (given g = 10m/s)

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.

here, P = 2kW = 2000W

h = 10 m, g = 10m/s , t = 1 min = 60s

using, P = W / t = mgh / t , we get

m = Pt / gh = 2000 x 60 / 10 x 10 = 1200kg
