Source of Data: 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_IAPWS, which incorporates the 1995 Formulation for the Thermodynamic Properties of Ordinary Water Substance for General and
Scientific Use, issued by The 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, “Formulations for the Thermodynamic Properties of the
Saturated Phases of H2O from 173.15 K to 473.15 K,” ASHRAE Trans., Part 2A, Paper 2793, 1983.

Source of Data: Tables A−11 through A−13 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 R-134a, which is based on the fundamental equation of state developed by R. Tillner-Roth and H.D. Baehr, “An International Standard Formulation for the
Thermodynamic Properties of 1,1,1,2-Tetrafluoroethane (HFC-134a) for temperatures from 170 K to 455 K and pressures up to 70 MPa,” J. Phys. Chem, Ref. Data, Vol. 23,
No. 5, 1994. The enthalpy and entropy values of saturated liquid are set to zero at −40°C (and −40°F).

* The entropy functions so and s+ corresponding to a thermodynamic temperature T are defined as s​​ ​​ o​ = ​s​​  o​(T ) = ​ ​  ​ ​[​​​c​  p​​(T ) / T​]​​dT​​ and s​​ ​​  +​ = ​s​​  +​(T ) = ​s​​  o​  − R ln T​and are used in the

entropy change calculations of ideal gases with variable specific heats, as discussed in Chap. 7.
