It has been found that the size of droplets originated by mixing depends not only on the interfacial tension and the parameters of mixing but also on the viscosity of the droplet and its surroundings. A semi-theoretical relationship has been proposed for the calculation of the size of the droplet. The validity of this relationship has been tested by measurements on ARD and RDC columns 250 mm in diameter and 1 m long.
