It isn't reasonable to expect mass transfer coefficients to be readily available for any and all systems. The "best" solution is to experimentally measure coefficients on a bench scale using a wetted-wall column, etc. When this isn't feasible, more approximate arrangements must be made. Dimensional analysis of mass transfer suggests correlations of the form: A number of correlations matching this form are presented in your textbook, pp. Treybal suggest the following correlations for use with beds packed with Raschig rings or Berl saddles: subject to the following definitions We will be using these in a class example. Since the basic mechanisms of heat, mass, and momentum transport are essentially the same, it is sometimes possible to directly relate heat transfer coefficients, mass transfer coefficients, and friction factors by means of analogies. Analogies involving momentum transfer are only valid if there is no form drag , hence they are pretty much limited to flow over flat plates and inside but not across conduits.
