Thermodynamics is viewed by many students as a diffi cult subject. Although the mathematics is rather simple, students fi nd the subject hard to understand. To improve comprehension, the concepts encountered in thermodynamics should be clearly stated and properly explained. We have, therefore, set out to write this book with the purpose of presenting a text that is rigorous and accurate, yet relatively easy to grasp. We assume that you have had at least one year of basic engineering education, including mathematics and physics.
A student who completes a course based on this book should be able to think in clear and correct thermodynamic terms, understand the basic principles of the subject, and gain suffi cient knowledge to solve real engineering problems. Some of the terms encountered in thermodynamics are also used in everyday life. Yet, terms that may be used loosely in day-to-day language have a very specifi c meaning in thermodynamics.
Thermodynamics has historically developed around the concepts of work, heat, energy, and temperature. In this book we defi ne each concept without ambiguity, in a manner that is easy to understand. Consider the following problem. An electric motor converts electrical energy into work at an effi ciency of 95%, whereas an automobile engine converts fuel energy into work at an effi ciency of less than 30%. Why is that so? Could the effi ciency be increased? If yes, what is the highest effi ciency that the best engine could attain?
Now consider another problem. An air conditioner uses electricity to remove heat from a cool room and transfer it to a warmer environment. Now if you turn around the air conditioner, you could use it in the winter to remove heat from a colder environment and transfer it into a warmer room. Such an arrangement is called a heat pump. Alternatively, you could employ a simple resistance heater that uses electricity to heat the room directly. What should you use and why?
After studying thermodynamics, you will know the exact answers to these and many other problems. The objective of this book is to provide the undergraduate student with a basic textbook on thermodynamics that is rigorous and accurate. There are many thermodynamic texts that present the subject in a scientifi cally correct manner; however, their presentation is at a level too high for the beginner. On the other hand, many of the popular basic texts on thermodynamics seem to lack in rigor. This book aims to bridge the gap between these two approaches.
Thermodynamics is viewed by many students as a diffi cult subject. Although the mathematics is rather simple, students fi nd the subject hard to understand. This is probably due to the fact that many concepts encountered by beginners have not been properly elucidated. The authors, therefore, set out to write this book with the purpose of presenting a text that is rigorous and accurate, yet relatively simple to grasp, presuming that the reader has had at least one year of basic engineering education, including mathematics and physics.
