An engine pumps water through a hose pipe. Water passes through the pipe and leaves it with a velocity of 2 m/s. The mass per unit length of water in the pipe is 100 kg/m. What is the power of the engine?
Multiple Choice Options
- A 400 W
- B 200 W
- C 100 W
- D 800 W
Step-by-Step Verified Solution
Here,
Mass per unit length of water, _ = 100 kg/m
Velocity of water, v = 2 m/s
Power of the engine, P = _ v 3 = (100 kg/m) (2 m/s) 3
= 800 W
