ESDU 76030 tabulates thermal conductivity values for temperatures from 240 K to 1500 K and pressures from 1 to 1000 atmospheres. Also tabulated is thermal conductivity of liquid and vapour along the saturation line. The values were derived by fitting an equation (as a function of density and temperature) to a range of experimental data taken from six sources; the density was computed using the 1973 IUPAC formulation. Alternative equations are given for the thermal conductivity of the saturated liquid and vapour; they are functions only of temperature and so are easier to use in process calculations, yet represent the tabulated data very closely.
