Uniform Barriers with a Source

Diffusion through Uniform Barriers with a Source 

The boundary conditions are g,- = go 6io, and go is maintained such that Co(0) = Co t) = constant other conditions being kept the same as in Case A. 

Equation (135), which is used to obtain (134), is obtained from (110a) and (129)  

The observation of (134) suggests that the following general rule to evaluate (133b) is valid  

Therefore, by using (136), (133b) reduces to the following form
