Chapter 20. Unsteady-State Mass Transfer
20.0 Chapter Objectives
On completion of this chapter, a student should be able to:
Derive the equation for unsteady-state mass transfer with and without chemical reaction
Use the Fourier series solution for unsteady-state diffusion in a flat plate with negligible surface resistance
Use convenient charts to help solve unsteady-state problems, where both internal and external resistances apply
Apply numerical, finite-difference methods for unsteady-state conduction problems
Derive the differential equation of energy change
20.1 Unsteady-State Diffusion
20.1A Derivation of a Basic Equation
In Chapters 18 and 19, we considered various mass-transfer systems where the concentration or partial pressure ...
