Abstract: The distribution of the sizes of drops in a rotary-disk, countercurrent extn. column was exptl. established for the water (continuous phase)- PhMe (dispersed phase) system by photographing the dispersion during interfacial substance transfer (Me2CO). The results were correlated with some published expressions for the drop-size distribution, and a relation between the parameters of convenient distribution and the quantities characterizing the hydrodynamic regime in equipment was derived. Moreover, the validity of some relations for the calcn. of mean diams. of drops was verified.
