Based on published drop size data in the absence of mass transfer, two equations for the prediction of drop diameter with a break‐point at disc Reynolds number equal to 50 000 are presented which predict the drop diameter to within 14%. The total range of disc Reynolds number covered is 1200 to 282 000. The same equations may be used when mass transfer occurs if only the preconstants are modified. The ranges of disc Reynolds number covered are 28 000 to 434 000 for transfer from the continuous to the dispersed phase and 9300 to 290 000 for transfer from the dispersed to the continuous phase, the average absolute relative deviation being 11% in both cases.
