Answer 2

Dear Student,

◆ Answer -

(4) 9 horse power

● Explaination -

# Given -

m/t = 250 kg/min = 250/60 kg/s

h = 150 m

# Solution -

Power required in drawing water from well is -

Power = mgh/t

Power = 250/60 × 10 × 150

Power = 6250 watt

Power = 6250/746 hp

Power = 8.378 hp

Therefore, only pump with more power i.e. 9 hp can be used for drawing water.

Thanks dear...
