15.5.2 Theoretically Derived Mass-Transfer Correlations

If the physical situation closely matches the assumptions made in the development of theoretically derived mass-transfer correlations, these correlations can be quite accurate. If the physical situation is somewhat different than the assumptions, the correlation may still be useful by using a small amount of experimental data to tune the coefficient. Practicing engineers would seldom do the derivations, but since they commonly use the results, it is important to know both the assumptions and the limits of validity of the correlation. The best way to understand these is to closely follow the derivation.

As a simple first example, consider the case of diffusion in a stagnant film (NB = 0) ...
