4.2.4 Example A: Diffusion between two layers

Course subject(s) 4. Mass transfer

We have two horizontal layers of liquid with the same thickness: top layer A, bottom layer B. In both, a component x is dissolved. Initially, the concentration of x in A equals twice the concentration in B, and is .

Furthermore, we know .

We would like to know: 1) Is x going from layers A to B or from B to A? 2) If I wait long enough, what will the concentration in both layers be?

Sorry but there don't seem to be any downloads..
