Thermodynamics DeMYSTiFied – Preface

This book is intended to accompany a text used in the first course in thermodynamics that is required in all mechanical engineering departments, as well as several other departments. It provides a succinct presentation of the material so that the students more easily understand the more difficult concepts. Many thermodynamics texts are over 900 pages long and it is often difficult to ferret out the essentials due to the excessive verbiage. This book presents those essentials. The basic principles upon which a study of thermodynamics is based are illustrated with numerous examples and practice exams, with solutions, that allow students to develop their problem-solving skills. All examples and problems are presented using SI metric units. English-unit equivalents are given in App. A. The mathematics required to solve the problems is that used in several other engineering courses. The more-advanced mathematics is typically not used in an introductory course in thermodynamics. Calculus is more than sufficient. The quizzes at the end of each chapter contain four-part, multiple-choice problems similar in format to those found in national exams, such as the Fundamentals of Engineering exam (the first of two exams required in the engineering registration process), the Graduate Record Exam (required when applying for most graduate schools), and the LSAT and MCAT exams. Engineering courses do not, in general, utilize multiple-choice exams but it is quite important that students gain experience in taking such exams. This book allows that experience. If one correctly answers 50 percent or more of multiple-choice questions correctly, that is quite good. If you have comments, suggestions, or corrections or simply want to opine, please email me at MerleCP@sbcglobal.net. It is impossible to write a book free of errors, but if I’m made aware of them, I can have them corrected in future printings

Basic Principles

Thermodynamics involves the storage, transformation, and transfer of energy. Energy is stored as internal energy (due to temperature), kinetic energy (due to motion), potential energy (due to elevation), and chemical energy (due to chemical composition); it is transformed from one of these forms to another; and it is transferred across a boundary as either heat or work. We will present equations that relate the transforma tions and transfers of energy to properties such as temperature, pressure, and density. The properties of materials thus become very important. Many equations will be based on experimental observations that have been presented as mathematical statements, or laws: primarily the fi rst and second laws of thermodynamics. The mechanical engineer’s objective in studying thermodynamics is most often the analysis of a rather complicated device, such as an air conditioner, an engine, or a power plant. As the fl uid fl ows through such a device, it is assumed to be a continuum in which there are measurable quantities such as pressure, temperature, and velocity. This book, then, will be restricted to macroscopic or engineering thermodynamics. If the behavior of individual molecules is important, statistical thermodynamics must be consulted.
