the existing measuremenjs of the viscosity of gaseous systems can be extended if use is made of statistical mechanics. in this work, we confine ourselves to the measurements of the viscosity of multicomponent mixtures of low-density gases. the method is applied to one sample of natural gas.

We formulate and study the model variational problem describing phase transitions in two-phase media. Based on this study, we obtain an information about properties of solutions to equilibrium a medium traditional statement.
