Question

A water pump rated 600 W , has an efficiency of 95 % . If it is used to raise water through vertical distance of 60 m . The volume of water drawn in 20 minutes, is [Use density of water = 1000 kg m - 3 , g = 10 m / s 2 ], 1 . 14 m 3, 2 . 24 m 3, 11 . 4 m 3, 22 . 4 m 3

MARKS App · Accepted Answer

Power of water pump to lift water is, P p = ρ V g h t , Effective power to raise water is given by, P p = η P R a t e d ⇒ P p = 0 . 95 × 600 = 570 W ⇒ ρ V g h t = 570 ⇒ 1000 × V × 10 × 60 20 × 60 = 570 ⇒ V = 570 × 20 × 60 1000 × 10 × 60 = 1 . 14 m 3
