SECTION 16: PRESSURE-VOLUME-TEMPERATURE AND PHASE RELATIONS OF WATER AND CARBON DIOXIDE

The relationships between the various forms of solid H 2O and solid-liquid H 20 equilibria are well understood owing to the extensive work of P. W. Bridgman [ 1,2, 4, 5,6], These relationships are shown in Figure 16-1. Bridgman's [ 3] curve for solid-liquid equilibrium in CO 2is also shown in this figure. The specific volumes of water in cm 3/gm as a function of pressure and temperature are given in Table 16-1. The sources of these data are as follows: 1 bar,0°-100° CTilton and Taylor [22]Owen, White, and Smith [19]10-1400 bars,0°-100° CBridgman [2] as recomputedby Goranson [9]1600-10,000 bars,90°-100° CBridgman [4,5]Vapor region,120°-l 80° CJuza [11] as tabulated byFaxenLiquid region to 350 bars,100°-360° CSmith and Keyes [21]400-2500 bars,120°-180°CInterpolatedVapor-100 bars,200°-1000° CKennedy [14]150-1400 bars,380°-800° CHolser and Kennedy [10]Kirillin, Rumyantsev, and Zubaryev [17]Keyes, Smith, and Gerry [16]1600-2500 bars,380°-600° CKennedy [12] corrected and smoothed1600-2500 bars,600°-800°CExtrapolated on isometrics150-2500 bars,850°-1000°CExtrapolated on isometrics5000-250,000 bars,120°-1000°CRice and Walsh [20]5000-50,000 bars,80°-180°CBridgman [7] Table 16-2, the specific volumes of water at saturation, are taken from Osborne, Stimson, and Ginnings [ 18], Tilton and Taylor [ 22], and Owen, White, and Smith [ 19].
