Semi-infinite vs. Finite Medium Assumptions | Bioengineering Mass Transfer
Whenever the system is at unsteady state, then you can make the semi-infinite or finite assumption. So how do we know which one to use? Either one should give you approximately the same answer, but one might make more sense and be easier to assume than the other. Here we outline when to use which assumption when solving mass transfer problems!
