✦ Synopsis

In derivation of all previous unsteady-state equations for prediction of mass transfer during formation of drops, it has been explicitly assumed that (i) the boundary layer around the drop is planar and, (ii) the concentration within the drop is reasonably constant. In the present work, it is shown that both these assumptions may be discarded by using the following expression for fractional approach to equilibrium, E, as a function of diffusivity, 0, distribution coetlìcient, H, drop diameter, d, and formation time, t,: where a.... = -a,-1,".
