For laminar flow through a closed conduit____________________?
Correct answer: A. Vmax = 2Vav
- A. Vmax = 2Vav
- B. Vmax = Vav
- C. Vmax = 1.5Vav
- D. Vmax = 0.5Vav
Explanation
For fully developed laminar flow in a circular pipe, the parabolic profile gives Vmax = 2Vav. The maximum velocity occurs at the centreline and is twice the cross-sectional mean.
