Question

250kg of water per minute is to be drawn from a well 150m deep . an electric pump f power _ can be used (g=10m/s^2)

Answer 1

Thus, the power of electric pump is 6250 Watt.

Step by step explanation:

mass of water, m = 250 kg

depth, h = 150 m

time, t = 1 min = 60 second

g = 10 m/s^2

Energy = m x g x h

E = 250 x 10 x 150

E = 375000 J

Power = Energy / Time

P = 375000 / 60

P = 6250 Watt.

Thus, the power of electric pump is 6250 Watt.
