We have found the logarithmic and arithmetic mean motive 
forces and the corresponding numbers of transfer units N in the vapor 
and liquid phases under complete mixing of a liquid. The efficiency 
values expressed in terms of N have been derived. It has been proved 
that the numbers of transfer units are equal in the complex model 
and the mass-exchange variants using the conditions for the coupling 
of an ideal and a real plate of the Murphree and Hausen models. The 
relationship between the N values under complete mixing and without 
it has been established.
