A simple model is proposed for mass transfer in a continuous phase around a single liquid drop. The model is based upon the assumption that the ratio of the average Sherwood number for a drop to that for its equivalent solid sphere is equal to the ratio of the local values at their front stagnation points. The available data for some binary systems are reasonably well correlated with the model, and it is theoretically more consistent than the analogical models proposed by Griffith, and Shirotsuka and Hirata which are based upon the boundary-layer analysis of the flow over a flat interface moving with a constant velocity.
