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
- AStatement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
- BStatement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
- CStatement 1 is true, Statement 2 is false.
- 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,
A v=A \propto At lower heights, speed will be more. Therefore, area of cross-section will be less. correct option is (a).
