Question

What do you mean by Sherwood number?

(a) Dimension mass transfer number

(b) Dimensionless mass transfer number

(c) Dimension momentum transfer number

(d) Dimensionless momentum transfer number

The question was posed to me in a job interview.

I'm obligated to ask this question of Convective Mass Transfer topic in portion Mass Transfer of Bioprocess Engineering

Answer 1

The correct option is (b) Dimensionless mass transfer number

To elaborate: The Sherwood number (Sh) (also called the mass transfer Nusselt number) is a dimensionless number used in mass-transfer operation. It represents the ratio of the convective mass transfer to the rate of diffusive mass transport, and is named in honor of Thomas Kilgore Sherwood.
