Question

if the power of a motor pump is 3kw.Then the volume of water in lit that can be lifted up to a height 10 m in 1 minute by the pump is

Answer 1

Given, power of pump = 3kW =3000W

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, 3000W = 100m/60s

Therefore, m = 1800kg

So, the pump can raise 1800kg of water in one minute.

Answer 2

Hey mate ^_^

Power of pump = 3000W

Time (t)= 60sec

Height (h) = 10m

g = 10m/s^2

Power = work done per unit time.

Work done = mgh = m ×10×10 =100m

Therefore,

3000W = 100m/60s

Therefore,

m = 1800kg

So, the pump can raise 1800kg of water in one minute.
