INTERRELATION BETWEEN MOVING FORCES IN SOME MODELS 
AND FORMS OF FLOW ORGANIZATION

The equality of the number of transfer units N in some 
models and variants of mass transfer and also for different forms 
of organization of vapor and liquid flows has been proved despite 
the difference in the expressions for N and quantities of mass-transfer 
efficiencies. Theoretical computations are confirmed by practical 
calculations. The constancy of the number of transfer units for all 
plates at the same operating parameters and closeness of logarithmic-mean 
and arithmetic-mean values of N are shown.
