Présentation de l'éditeur
This edition includes the subject matter of the first edition, entirely rewritten and rearranged, and in addition a considerable part of the material that was originally intended for a second volume on heat engines. The result is practically a new book. A new title, thermodynamics and heat engines might describe more accurately the purpose and scope of the book; since, however, the stress has been laid on principles rather than facts, even in the applications, the earlier title has been retained as sufficiently indicative of the character of the work. In the rewriting of the text the author has kept in view three principal objects. 1. To simplify and at the same time strengthen the presentation of the fundamental laws. In the earlier chapters the arrangement has been changed and more stress has been laid on important topics. The treatment of available energy and entropy, chapter V, has been worked out with special care. 2. To bring the book up to date. 3. To give an adequate presentation of the applications of thermodynamics to heat engines, air compression, and refrigeration. Considerable additions have been made to the subject matter, and a separate chapter has been devoted to each of the important applications. In the discussion of internal combustion engines the conventional aair standard treatment has been replaced by a fairly accurate analysis. As in the first edition, the text is copiously illustrated by problems, and in many cases the solutions are given in detail to show the student proper methods of computation. The number of exercises has been largely increased. The lists of references have been revised and brought up to date. The author acknowledges his indebtedness to the standard boots on thermodynamics and heat engines, in particular the works of Bryan, Preston, Griffiths, and Lorenz. He also acknowledges the generosity of manufacturers in sup

Présentation de l'éditeur
I ts purpose is to provide a course in the principles of thermodynamics that may serve as an adequate foundation for the advanced study of heat engines. As indicated by the title, emphasis is placed on the principles rather than on the applications of thermodynamics. In the chapters on the technical applications the underlying theory of various heat engines is quite fully developed. The discussion, however, is restricted to ideal cases, and questions that involve the design, operation, or performance of heat engines are reserved for a second volume. The arrangement of the subject matter and the method of presentation are the result of some twelve yeai Vexperience in teaching thermodynamics. Briefly, the arrangement is as follows :I nthe first six chapters, the fundamental laws are developed and the general equations of thermodynamics are derived. The laws of gases and gaseous mixtures are discussed in Chapters VII and VIII, and this discussion is followed immediately by the technical applications in which gaseous media play a part. A discussion of the properties of saturated and superheated vapors is likewise followed by the technical applications that involve vapor media. Some of the features of the book to which attention may be directed are the following: 1. The method of presenting the fundamental laws. In this treatment I have followed very closely the development in Bryan sthermodynamics. The second law is made identical with the law of degradation of energy, the connection between irreversibility and loss of availability is pointed out, and by means of the Carnot cycle a measure of availability is obtained.
