Question

Which number is analogous to Reynold’s number?

(a) Nusselt number

(b) Schmidt number

(c) Sherwood number

(d) Grashof number

I have been asked this question during an internship interview.

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

Answer 1

The correct answer is (d) Grashof number

The best explanation: The Grashof number (Gr) is a dimensionless number in fluid dynamics and heat transfer which approximates the ratio of the buoyancy to viscous force acting on a fluid. It frequently arises in the study of situations involving natural convection and is analogous to the Reynolds number.
