(b) Schmidt number

(c) Reynolds number

(d) Nusselt number

I had been asked this question in exam.

This key question is from Liquid- Solid Mass Transfer Correlations in division Heterogenous Reactions of Bioprocess Engineering

Answer 1

Correct option is (a) Sherwood number

The explanation: 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.
