The prediction of mass transfer rate in an internally circulating drop forming in a continuous gaseous medium depends upon the residence time of a liquid element on the drop surface. A theoretical analysis has been made for the estimation of this contact time. The experimental results on comparison with the model show that the mass transfer rate is inversely proportional to the square‐root of the contact time as conceived by a modified penetration theory.
