✦ Synopsis

The study of the mechanism of mass transfer in liquid drops as presented in Part I[11 of this paper has been continued and brought to an end.

A quantitative prediction of mass transfer can be presented now for the period of drop formation until the process of drop release sets in. Within the area studied no measurable deviation between the model of fresh surface elements and the experiments carried out do exist.

Mass transfer during the period of release after drop formation has also been studied and found to be quite considerable. It has been calculated as the difference between the total mass transfer as measured experimentally and the sum of all other contributions.

A high initial effect in mass transfer is also found for the period of drop rise. Coalescence of the drops provides an extremely low contribution to mass transfer.

Abstraet--A study of the rate of mass transfer to drops growing at a moderate speed has been made. The system used was that of isobutanol drops in a continuous water phase. A model for the behaviour of the different parts of a drop during formation and release has been proposed. On this basis a com
