Question

An electric pump has 2 kW power. How much water will the pump lift every minute to a height of 10 m?

Answer 1

Hello friend

__________________________

We have given:

Power (P) = 2 kW

1 kW = 1000 W

= 2 x 1000

= 2000 kW.

Height (h) = 10 m.

Time (t) = 1 min = 60s.

Acceleration due to gravity (g) =9.8 m/s^2.

We have to find:::

Mass of the water (m) = ????

So,we know that,

P = mgh/t

m = Pt/gh

m = 2000 x 60/9.8 x 10

m = 120000/98

m = 1224.5 kg.

Therefore, the water lifted by the pump is 1224.5 kg.

Thanks...... :)
