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.
and Statement 2 In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant.
Statement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
Statement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
Statement 1 is true, Statement 2 is false.
Statement 1 is false, Statement 2 is true
Solution
From continuity equation,
$
A v=\text { constant or } A \propto \frac{1}{v}
$
At lower heights, speed will be more. Therefore, area of cross-section will be less. $\therefore$ correct option is (a).
