Question

an electric pump Pass 2 kilowatt power how much water will the pump lift every minute to a height of 10 metre​

Answer 1

Answer:

1200 kg of water

Explanation:

• Power = Energy / Time

In this case energy is potential energy. So,

P = mgh/T

From above

m = PT / (gh)

= (2 kW × 1 min) / (10 m/s² × 10 m)

= (2 × 10³ W × 60 s) / (100 m²/s²)

= (120/100) × 10³ kg

= 1.2 × 10³ kg

= 1200 kg
