Question

Convective mass transfer involves the transportation of material between a boundary surface and a moving fluid or between two immiscible fluids. It is prescribed by the relation

(a) 2 h m (d C B)

(b) ½ h m (d C B)

(c) h m (d C B)

(d) 3/2 h m (d C B)

The question was posed to me during an interview.

My doubt stems from Convective Mass Transfer topic in portion Modes and Diffusion of Mass Transfer

Answer 1

The correct choice is (c) h m (d C B)

To elaborate: It is equal to m/A = h m (d C B).
