If a pump is capable of lifting 5000kg of water through a vertical height of 60m in 15 min, the power of the pump is

A. 2.25 x 10^5js−¹
B. 2.5 x 10^4js−¹
C. 3.3 x 10^3js−¹
D. 3.3 x 10^2js−¹

Correct Answer:

Option C – 3.3 x 10^3js−¹

Explanation

P = mgh/t

P = 5000×10×60/(15×60)s

P = 3333.3333

P = 3.3 x 10³js−¹
