This widely-used book of thermodynamic tables in the Système International(SI) or metric unit system has been thoroughly updated and revised. It basically comprises data on the thermodynamic, thermochemical, and transport properties of gases, including air, steam, refrigerants, and other fluids. A number of appendices define all units for the tables and give both exact and approximate conversion factors to British units and to some non-SI units. In the new edition of the book, the author has made a major change in the table of equilibrium constants to suit more generally accepted practice. Definitions of the basic SI units have also been updated.
