The ratio of maximum to average velocity in case of streamline flow between parallel plates is______________________?
Correct answer: B. 1.5
- A. 1
- B. 1.5
- C. 2
- D. 2.5
Explanation
Laminar flow between parallel plates has a parabolic velocity profile, with maximum velocity at the mid-plane. Integrating this profile gives an average velocity equal to two-thirds of the maximum, so the ratio is 1.5.
