# Explain Why A Fluid Flowing Out of a Small Hole in a Vessel Results in a Backward Thrust on the Vessel - Physics

Explain why A fluid flowing out of a small hole in a vessel results in a backward thrust on the vessel

#### Solution 1

This is because of principle of conservation of momentum. While the flowing fluid carries forward momentum, the vessel gets a backward momentum.

#### Solution 2

When a fluid flows out from a small hole in a vessel, the 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

Is there an error in this question or solution?
