The Consistency of the Thermodynamic Data for Water Substance Vapor Phase to 550°C. Part VII

A comprehensive investigation of the thermodynamic consistency of the large body of steam data above 150°C has been completed using the new thermodynamic scale information supplied by Professor J. A. Beattie to test the consistency of measured vapor pressures, specific volumes, enthalpies at saturation and superheat and specific heats. As an aid in correlation and unification a new form of equation of state is employed which has some validity through the critical region. The results of the investigation indicate a satisfactory state of thermodynamic consistency over the liquid‐vapor range with respect to vapor pressures and saturation volumes deduced from the measured vaporization quantities using the Beattie corrections to the international temperature scale. The consistency test includes also verification of the accuracy and usefulness of the new functional relation for the vapor phase, p=F(v, T) whose parameters were determined from the measured superheat p‐v‐T data. The superheat enthalpy data to 550°...
