Question

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

(a) Sh X = 0.332 (Re)^ 0.5 (Sc)^ 0.23

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

(c) Sh X = 0.332 (Re)^ 0.5 (Sc)^ 0.43

(d) Sh X = 0.332 (Re)^ 0.5 (Sc)^ 0.53

The question was asked by my college director while I was bunking the class.

My doubt is from Non Dimensionless Correlation for Convective Mass Transport in section Modes and Diffusion of Mass Transfer

Answer 1

Correct choice is (b) Sh X = 0.332 (Re)^ 0.5 (Sc)^ 0.33

The explanation: Sh = h ml/D = .332 (Re)^ 0.5 (Sc)^ 0.33.
