Question

the power of motor pumps is 2kw .how much water per minutes the pump can raiseto height of 10 m?

Answer 1

¿??????????????????????

Answer 2

Power = Work / Time

P = mgh / t

m/t = P/(gh)
= 2 × 10^3 Watt / (10 m/s^2 × 10 m)
= 20 kg/s

Motor pumps 20 kg of water for every 1 second.

In 1 minute (= 60 s) it pumps 60 × 20 kg = 1200 kg of water

So, final answer is 1200 kg/min
