Characteristic velocity was obtained in a pilot plant Hanson mixer-settler extraction column of seven stages
using three systems. In this paper, a set of previous characteristic velocity models presented in the past
literatures were examined. Comparison between these models and the experimental results showed that although
some of these equations may have satisfactory results, but they have to be more accuracy for design. So, a model
for prediction of slip velocity was suggested in terms of total holdup and characteristic velocity which depends on
physical properties of liquid systems and operating variables. The comparison of experimental values of slip
velocity was demonstrated good agreement with results of proposed model.
