Tables A-4 through A-8 are generated using the Engineering Equation Solver (EES) software developed by S. A. Klein and F. L. Alvarado. The routine
used In calculations is the highly accurate Steam_JAPWS, which incorporates the 1995 formulation for the Thermodynamic Properties of Ordinary Water
Substance for General and Scientific Use, issued by
‘International Association for the Properties of Water and Steam (IAPWS). This formulation replaces the
1984 formulation of Haar, Gallagher, and Kell (NBS/NRC Steam Tables. Hemisphere Publishing Co 1984), which is also available in EES as the routine
STEAM. The new formulation is based on the correlations of Saul and Wagner (J. Phys. Chem. Ref. Data. 16. 893, 1987) with modifications to adjust to the
International Temperature Scale of 1990. The modifications are described by Wagner and Pruss (J. Phys. Chem. Ref. Data. 22, 783. 1993). The properties of
ice are based on Hyland and Wexler.
