The lower critical value is less sensitive and is usually quoted simply as the "critical Reynolds number". Its value for smooth circular pipes and tubes is approximately 2,000.

The Correct answer is D.
Because critical Reynolds is between 2100-400.
Because critical Reynolds is between 2100-400.

The answer is None of These
Critical Reynolds number lies between transition regions (approx 2300).
Critical Reynolds number lies between transition regions (approx 2300).

Critical Reynolds number.
R>2000 and R<4000.
R>2000 and R<4000.

Yes, It should be 2300.

Critical Reynolds number means the number from where the flow is changing from laminar flow to turbulent flow. Since below 2100 is laminar, and 2100-4000 is transverse flow. So, the critical Reynolds number is lies around 2100-2300.
