Assertion (A): The thickness of boundary layer cannot be exactlydefined. 
Reason (R): The Velocity within the boundary layer approaches theinviscid velocity asymptotically.
  • a)
    Both A and R are individually true and R is the correct explanation of A
  • b)
    Both A and R are individually true but R is not the correct explanation of A
  • c)
    A is true but R is false
  • d)
    A is false but R is true
Correct answer is option 'A'. Can you explain this answer?

Assertion (A): The thickness of boundary layer cannot be exactlydefine...


Explanation:

The boundary layer is a thin layer of fluid adjacent to a surface where the velocity of the fluid is influenced by the presence of the surface. The thickness of the boundary layer is not a fixed value but varies depending on factors such as the Reynolds number and the nature of the flow.

Reasoning:

- Assertion (A): The thickness of boundary layer cannot be exactly defined.
- This statement is true because the boundary layer is a complex phenomenon and its thickness is influenced by various factors. It is not a uniform value and varies along the surface.

- Reason (R): The Velocity within the boundary layer approaches the inviscid velocity asymptotically.
- This statement is also true. As we move away from the surface, the velocity within the boundary layer gradually approaches the inviscid velocity of the fluid. This asymptotic behavior is a characteristic of boundary layers.

Therefore, both the assertion and reason are individually true. Furthermore, the reason provides a correct explanation for why the thickness of the boundary layer cannot be exactly defined, as it highlights the asymptotic nature of velocity within the boundary layer.
