Question

For flow of a fluid to be turbulent:

• A. fluid should have high density
• B. velocity should be large
• C. reynold number should be less than 2000
• D. both (a) and (b)

Answer 1

Answer: (D)

both (a) and (b)

1) For turbulent flow both velocity and density of fluid should be high.

2) Value of reynold's number $Re>4000$

note $Re<2000$ is for laminar flow and $2000<Re<4000$ transition flow.
