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.

Options

  1. AStatement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
  2. BStatement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
  3. CStatement 1 is true, Statement 2 is false.
  4. DStatement 1 is false, Statement 2 is true

Correct answer

A. Statement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.

Step-by-step solution

From continuity equation, Av= constant or A∝1vA 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).
