The dimensionless group in mass transfer that is equivalent to Prandtl number in heat transfer is_________________?
Correct answer: D. Schmidt number
- A. Nusselt number
- B. Sherwood number
- C. Stanton number
- D. Schmidt number
Explanation
The Schmidt number, Sc = ν/D, compares momentum diffusivity with mass diffusivity. It plays the same role in mass transfer that the Prandtl number, Pr = ν/α, plays in heat transfer.

In a laboratory test run, the rate of drying was found to be 0.5 x 10^-3 kg/m2.s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m2/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is______________________?
