ESDU 88016 tabulates the density, isobaric specific heat capacity, specific enthalpy, viscosity and thermal conductivity of the liquid and vapour phases together with the vapour pressure, latent heat of vaporisation and surface tension at 10 K intervals along the saturation line from the melting to the critical point. For the ideal gas, in addition, the enthalpy, isobaric specific heat capacity, viscosity and thermal conductivity are tabulated at 20 degree intervals in degrees Celsius and kelvin from the melting point to 1000 K at atmospheric pressure. The saturation data were obtained from an evaluation of the experimental data drawn from the literature and extrapolated values are indicated. Although the data are given in SI units, conversion factors to other common engineering units are included.
