In a mixer, the quantity, (v. L/D) is termed as __________ number (where, v = longitudinal velocity of material, L = length of the mixer, D = diffusivity in axial mixing) ?
Correct answer: A. Peclet
- A. Peclet
- B. Weber
- C. Brinkman
- D. Schmidt
Explanation
The ratio vL/D compares convective transport over the mixer length with axial diffusive mixing, which is the Peclet number. Weber, Brinkman, and Schmidt numbers use different physical ratios.
