WebFeb 2, 2011 · One more example of mass transfer is diffusion of some substance, such as A from one moving medium to another through interface (two-film theory). If it is assumed that there is no concentration jump on the boundary, i.e., C ABi = C AEi (Fig. 1a), then the flow of substance A can be represented in the form WebWatch the entire series for Bioprocess Technology on my channel Thanks!
