Laminar flow of a Newtonian fluid ceases to exist, when the Reynolds number exceeds___________________?
Correct answer: B. 2100
- A. 4000
- B. 2100
- C. 1500
- D. 3000
Explanation
For pipe flow, laminar flow is generally limited to Reynolds numbers below about 2100; above this value, transition begins. The range from roughly 2100 to 4000 is transitional rather than fully turbulent.
