Question

the power of a motor pump is 2 kw. how much water per minute the pump can raise to a height of 10m ?

Answer 1

Answer:

The answer is 1200 kg.

Explanation:

Here is the formula of the power:

Power =work done per unit time.

Given data:

Power of pump = 2 KW =2000 W  

Time (t)= 60 sec  

Height (h) = 10 m  

g = 10 m/s2  

As we know that:

Work done = m x g x h = m ×10×10 =100 m  

Therefore, 2000 W = 100 m/60 s  

Therefore, m = 1200 kg  

So, the pump can raise 1200 kg of water in one minute.
