Presents the results of the authors' independent correlation of all new experimental and all previously existing data on thermodynamic and transport properties of water, replacing the widely used Keenan and Keyes tables. The whole body of high-quality experimental data on liquid and vapor water has been faithfully represented by a single fundamental equation from which all thermodynamic properties can ve calculated for any state. Tables are given in SI units. This edition replaces the International Metric Units edition published in 1969.
