Question

.Calculate the power of a pump which can lift 500kg of water through a vertical height of 12m in 0.3 minutes ,assuming g =9.8m/s

Answer 1

Answer:

3266.6 W

Explanation:

Given,

mass = 500 kg

height = 12 m

time = 60 x 0.3 = 18 s

Potential energy = mgh

Power = Energy / Time = mgh/t

= 500 x 9.8 x 12 / 18 = 3266.6 W
