Abstract:

A correlation of free volume of saturated vapor with that of coexisting liquid phase is derived from the cell theory of flulds. Then this correlation is combined with a revised free volume model proposed by this author for viscosity and thermal conductivity, equations are derived which correlate the viscosities and thermal conductivities of coekisting vapors and liqueds with heat of vaporization and temperature. The literature data for 44 representative substances are used to test the equations and the results are satisfactory. It can be seen from this work that there might exist some relations between the transport properties of vapors and those of coexisting liquids.

Key words: Viscosity, Thermal conductivity, Saturated Vapors, Liquids phase, Heat of vaporization, Temperature
