Thermal conductivity Missenard method

The graphs for liquids are based on both experimental data and estimates. Estimates for liquid thermal conductivity were primarily based on modified Missenard and Pachaiyappan methods. Both experimental data and estimates were then regressed to provide the same equation with wide and extended temperature coverage for all compounds. 

Liquids The Baroncini method provides accurate liquid thermal conductivity estimates if the compound clearly belongs to one of the specific families designated by the correlation. The Sastri-Rao method is recommended for other specific families as listed in the discussion of the method given below. As a general method for estimating thermal conductivity of pure liquids at ambient pressure for all other compounds, the Missenard method is recommended. 

The pressure dependence of the liquid thermal conductivity can usually be neglected. At very high pressures, it can be taken into account with the Missenard method [6] ... 

Several methods for the estimation of liquid thermal conductivities are presented by Reid etal. (1987), namely, the method of Latini and co-workers (Latini Pacetti 1978 Bar-roncini etal. 1980,1981,1983a,b, 1984), the Sato-Riedel method and the Missenard-Riedel method (Riedel 1949,1951a,b,c Missenard 1973). The Latini method employs different parameters for compounds from different families, such as acids, esters, etc., while the other two methods are simply equations that give the thermal conductivity as a function of the molar mass and the reduced temperature. For example, the Sato-Riedel equation reads...
