Question

7. An electric pump has 2KW power. How much water will the pump lift every minute to a

height of 10m?

​

Answer 1

Answer:

Given,

Power = 2kw = 2000w , Height H = 10m , Time taken t = 60 seconds.

Now ,

Power = Energy/time = mgh/t

2ooo = m*10*10/60

We get m = 1200 kg

Therefore , the pump lifts 1200 kg or 1200 l of water to a height of 10m every minute
