A model of breakage of drops in a stirred vessel has been proposed to account for the effect of rheology of the dispersed phase. The deformation of the drop is represented by a Voigt element. A realistic description of the role of interracial tension is incorporated by treating it as a restoring for

The model of dispersion proposed by Coulaloglou and Tavlarides is compared with published results from experiments in hatch stirred tanks. An alternative to this model is developed by introducing a different formula for the efficiency of collisions-the mechanism of coalescence of drops by film drain
Using the theoretical procedure outlined in the first part of this work, breakage and coalescence rates were determined experimentally in a stirred tank. After reaching steady-state conditions, the intensity of agitation was suddenly changed and the variation in drop size distribution with time was
