The influence of liquid mixing on mean logarithmic and 
arithmetic forces as well as the numbers of transfer units in direct 
flow has been studied. The extreme cases where liquid on the plate 
is entirely mixed and where it moves in a regime of perfect displacement 
are considered. The interrelationship between the mean arithmetic 
forces and numbers of transfer units in the case of complete liquid 
mixing and without it has been found. Dependences of the efficiency 
on the numbers of transfer units are determined.
