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 resisi-tances apply.
Apply numerical, finite-difference methods for unsteady-state conduction problems.
Derive the differential equation of enery change
