This is an introductory text on the principles and applications of engineering thermodynamics and elementary heat transfer. The reader is presumed to have a knowledge of college physics and mathematics, including elementary calculus. With the exception of the chapter on heat transmission, the material in this book is derived directly from my earlier one, Mechanical Engineering Thermodynamics, mainly by omitting sections that appeared to be unnecessary for a shorter course. Most of the omissions are from the chapters on applications. In this book, as in the longer one, thermodynamics is treated as a logical formulation of facts known from experience, with emphasis on the generality of the subject. The purpose of the book is to help the reader toward understanding the subject, rather than to confer facility in solving type problems. Nevertheless, since experience shows that understanding must be built up from a foundation of familiarity with small details, the derivations and basic applications are explained in considerable detail, and many worked examples are given.
As a further aid to understanding, the following types of concepts, often confused in a reader's mind, are carefully identified as they appear: facts from experience; principles accepted because they are confirmed by experience; arbitrary definitions, chosen on the basis of their utility for specific purposes; approximations like the gas laws, used because physical data do not conform to simple mathematical formulations; conventions, devices for facilitating thought and communication.
The first part of the book deals with work, heat, and the First Law as applied to general systems. The steady flow equations are then developed to provide material for application of the basic concepts. The Second Law is presented as a formal statement of the existence of irreversibility, and the thermodynamic temperature scale is defined as a corollary of the Second Law. Entropy is defined, and stated to be a property, but no proof is given.
The properties of substances are presented first from a general viewpoint, using plots to show the relationships among gaseous, liquid, and solid states. Then the special methods of handling property data are explained, with reference to steam table data, gas law data, properties of gaseous mixtures, and gas table data.
In the chapters on applications there is less detail than in the earlier book, but within the narrower scope the object is the same: to show the application of thermodynamics in heat engineering, without going into details of plant engineering, but taking care to point out that thermodynamics shows only one aspect of the total problem.
In the chapter on heat transmission I have tried to combine enough explanation to give a reasonable physical picture, with enough for* mulas and data to permit some approach to realistic problems. A single chapter, written from this approach, must be sharply limited in scope, but there is sufficient material for the usual short treatment. Because most students now encounter dimensional analysis in fluid mechanics, the development of the dimensionless groups as been omitted to save space.
While it is desirable in any case for an instructor to discuss in more detail, as opportunity arises, various points that are not covered in detail in the text, this is especially desirable with a condensed book. My longer book would provide some material for this purpose, and the references given at the ends of the chapters should also be consulted.
