The main equation of the theory received due to the conservation law of dissipative functions of the vapor – liquid system. The diapason of drop size it’s finding when its stability. It’s comparison of the results with the famous classical is given. The numerical estimate of the linear size of small disperse phase when take place usually evaporation (i.e. the Knudsen’s number is a small Kn = l R ≪ 1, where l is a free length path of the molecule and R is an drop radius) are given.
