equal to perimeter of the unperturbed cross section of the jet. An increase of the initial amplitude by a factor of e results in = 1, or 

The wavelength (17.67) of these perturbations that was found earher can be considered as the distance between drops into which the jet will split. A drop of diameter d will be formed from the liquid contained in the cylinder of length 

Flow Caused by a Surface Tension Gradient - The Marangoni Effect 

A model that pictures the interface as a thin layer with high viscosity (the Bous-sinesq model [2]) has gained widespread acceptance. For such a layer, one has to write down a special phenomenological correlation that connects the surface stress tensor with the rate of surface strain tensor [25). Paper [26] uses this model to examine the problem of the influence of surfactants on the dynamics of a free interface.
