The transient concentration profile c A (z,t) resulting from transient one-dimensional diffusion in a slab under conditions

Question:

The transient concentration profile cA(z,t) resulting from transient one-dimensional diffusion in a slab under conditions of negligible surface resistance is described by equation (27.16). Use this equation to develop an equation for predicting the average concentration, c̅A, within the control volume at a given time t. Then evaluate and plot the dimensionless average profile (c̅A – cAs) (cA0 – cAs) as a function of the dimension less relative time ratio, XD. Use a spreadsheet to perform the
calculations needed to implement the infinite series analytical solution.
