Curation notes#

Identity VALIDATED_WITH_WARNINGS by the library. Pages are pdf pages.

IDEAL GAS AND CONSTANTS: R = 8.31434 J/(mol K), M = 31.9988 g/mol; the ideal-gas part (Eq. 15, p. 11; Table 3, p. 12) is that of Wagner, Ewers and Schmidt (1982), valid 30-3000 K, with no uncertainty stated. The equation’s range is 54-300 K, 818 bar.

AGAINST COOLPROP 8.0.0 (reference key Schmidt-FPE-1985, Stewart-JPCRD-1991): CoolProp’s ideal part is a refit of this equation, which Stewart et al. print as their Eq. (11) (stewart_1991): within 3.3e-6 from 60 K to 1500 K, parting above (TC-765).
