Velocity distribution for flow between two fixed parallel plates_________________?
Correct answer: A. Varies parabolically across the section
- A. Varies parabolically across the section
- B. Is constant over the entire cross-section
- C. Is zero at the plates and increases linearly to the mid-plane
- D. None of these
Explanation
Fully developed laminar flow between fixed parallel plates has a parabolic velocity profile, with zero velocity at each stationary plate and maximum velocity at the mid-plane. It does not increase linearly to the centre, so option C is not correct.
