Transition length for a turbulent fluid entering into a pipe is around _____________ times the pipe diameter?
Correct answer: B. 50
- A. 5
- B. 50
- C. 500
- D. 5000
Explanation
The turbulent entrance length is commonly taken as about 10 to 60 pipe diameters, with 50 diameters used as a standard estimate. Laminar flow develops much farther downstream, often around 0.05 Re times the diameter.
