Assertion : The flow is turbulent for Reynolds number greater than 2000. Reason : Turbulence dissipates kinetic energy in the form of heat.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Both are separate facts Reynold number \(=\left(\dfrac{\text { Inertial force }}{\text { Viscous force }}\right)\) The flow is considered streamline or laminar when the Reynolds number is less than 2000, and it becomes turbulent when the Reynolds number exceeds 2000 . So correct option is (2).

Assertion : For Reynold number \(R_{e}>2000\), the flow of fluid is turbulent. Reason : Inertial forces are dominant compared to the viscous forces at such high Reynold numbers
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
\(R_{e}=\left[\dfrac{\text { Inertia force }}{\text { Viscous force }}\right]\) A Reynolds number above 2000 generally indicates turbulent flow. This is because at high Reynolds numbers, inertial forces dominate over viscous forces, leading to turbulent flow. So correct option is (1).
