We gratefully acknowledge the contributions of Professor Charles Mucken-fuss, of Debra L. Saucke, and of Eugene N. Dorsi, whose efforts produced computer programs for calculation of the thermodynamic properties of steam and ultimately the Steam Tables of App. C. We would also like to thank the reviewers of this edition Stanley M. Walas, University of Kansas Robert G. Squires, Purdue University Professor Donald Sundstrom, University of Connecticut and Professor Michael Mohr, Massachusetts Institute of Technology. Most especially, we acknowledge the contributions of Professor M. M. Abbott, whose creative ideas are reflected in the structure and character of this fourth edition, and who reviewed the entire manuscript. 

This obvious relationship is used in Table 5.11 to obtain mass-fraction averages of thermodynamic properties of steam-condensate mixtures. The macroscopic energy balance, is used to obtain the steam flow rate. Like compressors, the kinetic and potential energy terms are not significant, and the expansion is assumed to be adiabatic.

Thermodynamic properties of steam from the Steam Tables Initial conditions ... 

Extensive thermodynamic properties of steam are available in the steam tables and these data offer a good comparison for the validity of the equation of state in the calculation of other thermodynamic properties. Figure 1 shows the fugacity coefficients of steam calculated from Equation 15. For comparison, Figure 1 also shows the fugacity coefficients of steam calculated from the steam tables. 

Solution. The hot load is of 7000 kW, the hottest stream being at 180 °C. If zl71 j,i=30 °C is assumed for utility/process exchange, the minimum steam temperature is 210 °C, or a saturation pressure of approximately 20 bar. Thermodynamic properties of steam in different conditions as required by the problem are given below (see also Atmex F) ...

To facilitate steam-cycle calculations, standard tables of the thermodynamic properties of steam can be used. The data contained in these tables are plotted on a Mollier diagram (Fig. T-65), which is employed extensively to solve thermo mamic problems relating to steam turbines.
