ESDU 89020:1990

ESDU 89020 tabulates in SI units from the melting point to the critical point along the saturation line at fixed pressures data for: saturation temperature, liquid density, vapour specific volume, liquid and vapour enthalpy and entropy, latent heat of vaporisation and specific heat capacity. In addition, tables give along specific isobars for pressures up to 50 MN/sq m the variation with temperature for the vapour of specific volume, compression factor, enthalpy, entropy, and specific heat capacities at constant pressure and volume. The data were generated from a single correlating function fitting selected experimental data drawn from the literature, and are therefore self-consistent. An estimate of the error in linear interpolation within the tables is included, and a computer- generated temperature-enthalpy chart representing the data is provided. To facilitate use of the data in British units, conversion factors are given. No equations for the values are included.
