Question

Find the power in pumping 3425 meter cube of water per hour from a well 8 m deep to the surface, supposing 40%of the horse power during pumping is wasted. What is the horsepower of the engine???​

Answer 1

Hey buddy,

● Answer- Horsepower = 170 hp

● Explaination-

# Given-

V/t = 3425 m^3/hr = 0.9514 m^3/s

h = 8 m

Power lost = 40%

# Solution-

Output power required here is-

Power = Work done/time

Po = mgh/t

Po = V×ρ×g×h/t

Po = 0.9514×1000×10×8

Po = 76112 W = 76.112 kW

Input power is given by

Pi = Po/η

Pi = 76112/60%

Pi = 126853 W

Horsepower is

P = Pi/746

P = 126853/746

P = 170 hp

Horsepower of the engine is 170 hp.

Hope that helps you...
