Question

In laminar flow through a pipe, velocity profile is:
  1. A
    Uniform across cross section
  2. B
    Parabolic (maximum at centre)
    Correct
  3. C
    Maximum at walls
  4. D
    Linear from wall to centre

Correct answer

Parabolic (maximum at centre)

Explanation

Poiseuille flow: v(r) = v_max(1 − r²/R²). Velocity is maximum at centreline and zero at walls (no-slip condition).
