STATEMENT-1 : 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.
STATEMENT-2 : In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant.
STATEMENT-2 : In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant.
View answer and explanation
Correct option: A
Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1
Option A is correct. Statement-1 is true because of the continuity equation, and Statement-2 correctly explains why the water stream spreads or narrows based on velocity changes.
