Theoretical models for the drainage of the liquid film between a droplet and the interface have been presented in which the thickness of the film is assumed to vary. The models have been used to derive expressions for the film drainage time and the pressure drop through the film. The experimental results presented in Part I of this paper, when inserted into the equations, show that the drainage film is thinnest at its periphery. These conclusions have been supported by high‐speed photography and have been used to explain the distribution of coalescence times reported by all investigators in this field.
