The Schmidt number which is defined as, μ/ρ D, is the ratio of the_____________________?
Correct answer: A. Momentum diffusivity to the mass diffusivity
- A. Momentum diffusivity to the mass diffusivity
- B. Thermal diffusivity to the mass diffusivity
- C. Momentum diffusivity to the thermal diffusivity
- D. None of these
Explanation
The Schmidt number is Sc = ν/DAB = (μ/ρ)/DAB, so it is the ratio of momentum diffusivity to mass diffusivity. Thermal diffusivity appears instead in the Prandtl number.
