Question
Assertion :The stream of water flowing at high speed from a garden hose, pipe tends to spread like a fountain when held vertically up but tends to narrow down when held vertically down. Reason: In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant.

Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant. When stream of water moving up with speed, the speed decreases as it goes higher and thus the cross sectional area of movement of water increases to maintain the volume flow rate of water and thus spreads like fountain.Similarly when moving down, the speed of flow of water increases and hence the cross sectional area of flow decreases to maintain the volume flow rate.
