Turbulence and Mixing - GATE ME '14 S3
Consider the turbulent flow of a fluid through a circular pipe of diameter, D.
Identify the correct pair of statements. I. The fluid is well-mixed II. The fluid is unmixed III. ReD<2300 IV. ReD>2300 A. I, III B. II, IV C. II, III D. I, IV
Ans: For a turbulent flow, the Reynolds number is greater than 2300.
The fluid gets well mixed in turbulent flow compared to laminar flow.
