Chapter 19. Steady-State Mass Transfer

19.0 Chapter Objectives

On completion of this chapter a student should be able to:

• Calculate diffusion fluxes for the two classic cases: a) Equilmolar counterdiffusion and b) A diffusing through stagnat, nondiffusing B

• Calculate diffusion fluxes through a varying cross-sectional area

• Calculate diffusion fluxes for multicomponent system of gasses

• Calculate diffusion fluxes for diffusion in solids, by using the additional concepts of solubility, permeability, tortuosity and void fraction.

• Calculate the Knudsen number for a gases and determine the appropriate diffusion coefficient.

• Calculate the diffusion fluxes in situations where both diffusion and chemical reaction occur.

• Use the numerical ...
