Question
Explain why:
(d) A fluid flowing out of a small hole in a vessel results in a backward thrust on the vessel
Solution
When a fluid flows out from a small hole in a vessel receives a backward thrust.
A fluid flowing out from a small hole has a large velocity according to the equation of continuity.
Area × Velocity = Constant
According to the law of conservation of momentum, the vessel attains a backward velocity because there are no external forces acting on the system
