The authors obtained generalized dependences for the 
heights of transfer units of ideal and actual steps that are expressed 
by the parameters of an actual tray in the vapor and liquid phases. 
The particular dependences of the heights of the transfer units equivalent 
to a theoretical tray that are expressed by the parameters of an actual 
tray in the vapor phase are presented for four variants of interrelation 
between the ideal and actual trays, two of which are characteristic 
of the Murphree model in analyzing the efficiency in the vapor and 
liquid phases and one of which is characteristic of the Hausen model. 
The ratio of the heights of the ideal and actual trays in all the 
variants is equal to the efficiency. It is noted that the expressions 
of the average moving forces, the mass-transfer coefficients, and 
the numbers of transfer units are individual for each variant and 
form of organization of phase motion, but in generalized form they 
are given by the existing dependences.
