The velocity distribution in direction normal to the direction of flow in plane Poiseuille flow is_______________________?
Correct answer: B. Parabolic
- A. Hyperbolic
- B. Parabolic
- C. Linear
- D. None of these
Explanation
For fully developed laminar flow between parallel plates, the velocity profile is parabolic because the pressure-gradient force is balanced by viscous shear. The velocity is maximum at the mid-plane and zero at the walls.
