The thermodynamic properties of water and water vapor

Extensive international research has been conducted within about the last 10 years for the purpose of ascertaining, with maximum accuracy, the thermodynamic properties of water and water vapor. Experiments were carried out to this end at the National Bureau of Standards, the Massachusetts Institute of Technology, and Harvard University in the United States; and other experiments were conducted by agencies in England, Germany, and Czechoslovakia. By international conferences, the individual findings of these agencies were then collected and cross-checked for consistency by means of the general thermodynamic equations; when inconsistencies were disclosed, the apparatus was investigated and the data redetermined. The final results have been made available in this country in tables of the Thermodynamic Properties of Steam, prepared by J. H. Keenan and F. G. Keyes of the Massachusetts Institute of Technology (New York, John Wiley and Sons, 1936)
