Effective Surface Area of Drops during Their Formation

At level direction

Abstract

Six substances were used as the dispersed phase and photographs of drop formation were continuously taken by video camera so that their effective surface area could be measured.
It was found that the ratio of effective surface area to nozzle area has the following relation to Bond number and relative time :
A/A_N=6.1 (N_BO)^-0.72 (T_f) ^0.8
0.015<N_BO<0.9
0.2<T_f<10
