Vedclass · Answer

(A) As water falls from a tap,it accelerates due to gravity,so its velocity $v$ increases as it moves downwards.According to the equation of continuity for an incompressible fluid,the product of the cross-sectional area $A$ and the velocity $v$ remains constant: $A \cdot v = 	ext{constant}$.Since $v$ increases as the water falls,the cross-sectional area $A$ must decrease to keep the product $A \cdot v$ constant.Therefore,the area of the water stream decreases.

When water falls from a tap,what happens to the cross-sectional area of the water stream as it moves downwards?
