Fluid Dynamics: Practice Problem & Solution
Assertion (A): In streamline flow streamlines never intersect each other. Reason (R): If streamline intersect then their must two velocities of fluid particle at the point of intersection, which is impossible.
Short Solution (Best for NEET):
To solve this problem, we apply the core principles of Fluid Dynamics. Understanding the underlying formula is key to arriving at the correct answer below:
Assertion (A) is true by definition of streamline flow.
Reason (R) is true because intersection would imply multiple velocity vectors at a single point, which is physically impossible.
(R) correctly explains (A).
