Given below are two statements: Statement (A): The flow in a pipe is turbulent when the Reynolds’ Number is more than 4000. Statement (R): The flow in a pipe is turbulent at entry and slowly changes to laminar along the length of the pipe. In light of the above statements, choose the correct answer from the options given below:
Show Hint
Turbulent flow occurs when the Reynolds number exceeds 4000 The flow does not typically transition to laminar within the same pipe under constant conditions
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
(A) is true but (R) is false.
(A) is false but (R) is true

The Correct Option isC
Solution and Explanation
Statement A is correct because the flow is generally considered turbulent when the Reynolds number exceeds 4000 However statement R is incorrect because turbulent flow does not transition to laminar flow over a pipe’s length it remains turbulent unless external factors alter the flow
