Assertion: The flow is turbulent for Reynolds number greater than `2000`.
Reason: Turbulence dissipates kinetic energy in the form of heat.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

if assertion is true but reason is false.

D

if both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
The flow is streamline or laminar for Reynolds number less than `1000` and flow is turbulent for Reynolds number greater than `2000`.
