Corresponding to Prandtl number in heat transfer, the dimensionless group in mass transfer is the _______________ number?
Correct answer: D. Schmidt
- A. Stanton
- B. Sherwood
- C. Peclet
- D. Schmidt
Explanation
The Schmidt number, Sc = ν/D, compares momentum diffusivity with mass diffusivity, just as the Prandtl number compares momentum diffusivity with thermal diffusivity. Sherwood number instead represents a mass-transfer analogue of the Nusselt number.
