Question

The empirical correlation for local mass transfer coefficient for turbulent boundary layer flow past a flat plate is given by

(a) Sh X = 0.332 (Re)^ 0.5 (Sc)^ 0.33

(b) Sh X = 0.332 (Re)^ 0.6 (Sc)^ 0.33

(c) Sh X = 0.0298 (Re)^ 0.7 (Sc)^ 0.33

(d) Sh X = 0.0298 (Re)^ 0.8 (Sc)^ 0.33

This question was posed to me in final exam.

The above asked question is from Non Dimensionless Correlation for Convective Mass Transport in portion Modes and Diffusion of Mass Transfer

Answer 1

Correct choice is (d) Sh X = 0.0298 (Re)^ 0.8 (Sc)^ 0.33

Easiest explanation: Sh = h ml/D.
