Assertion: The flow of fluid is said to be steady if at any given point, the velocity of each passing fluid particle do not remain constant.
Reason: The path taken by a fluid particle under a steady flow is a turbulent.
Reason: The path taken by a fluid particle under a steady flow is a turbulent.
View answer and explanation
Correct option: D
If both assertion and reason are false
Option D (If both assertion and reason are false) is correct because in steady flow, the velocity at a given point remains constant, and the path taken is a streamline, not turbulent.
