Question

A pump is required to lift 1000 kg of water in 1 minute from a well
of depth 10 m and eject it with a speed of 10 m/s What is the
horsepower of the pump? [Assume g=10 m/s2]

Dear Student
Work done by the engine = PE gained by the water = (1000 Kg) X
(10 m/s2) X (10 m) = 105 J
Time taken = 1 min = 60 s
Power of the engine = (105/60) W
1 hp = 745 7 W
Implies, (105/60) W = 2 235 hp
