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.Re_D < 2300
IV. Re_D > 2300

1. I and III
2. II and IV
3. II and III
4. I and IV

Correct Option: D

Re_D > 2300 means it is a turbulent flow. I n turbulent flow, the fluid is well mixed. The fluid is unmixed, for a very-low Reynolds number laminar flow.
