This web resource is intended to be a totally self-contained learning resource in Engineering Thermodynamics, independent of any textbook. It is designed to be suitable for a two course sequence for Mechanical Engineering majors, however it can be used in any format, including that of self-study.

In Part 1 we introduce the First and Second Laws of Thermodynamics, however rather than describing these in terms of processes and components we have chosen the more interesting approach of their synthesis into complete cycles or systems. Thus we evaluate complete ideal heat engines, steam power plants and refrigeration systems in Chapters 3 and 4. Wherever appropriate, rather than relying on equations and tables to evaluate the performance of these systems we introduce graphical two-dimensional plots to enable intuitive visualization of the solutions to a high degree of accuracy.
| Chapter 1: Introductory Concepts, Units, and Definitions |
|
Chapter 2: Properties of Pure Substances |
|
Chapter 3: The First Law of Thermodynamics for Closed Systems
|
|
Chapter 4: The First Law of Thermodynamics for Control Volumes |
| Chapter 5: The Second Law of Thermodynamics |
|
Chapter 6: Entropy - A New Property We present an Entropy Summary Sheet, Isentropic Processes Summary Sheet, and an Adiabatic Efficiency Summary Sheet of all the relevant equations relating to this Section. |
In Part 2 we introduce the concept of Exergy to determine theoretical limits of performance of various thermodynamic components and systems, followed by advanced application of steam power plants. The chapter on Carbon Dioxide as a refrigerant does not appear in any textbook that I am aware of, however because of the current Global Warming crisis, the currently used refrigerant R134a will be banned from usage in automobile air conditioning systems in Europe within a few years. The alternative being developed is a return to Carbon Dioxide as the refrigerant of choice. Finally we introduce mixtures of water vapor and air and their application in air-conditioning and cooling tower systems, and conclude with an introduction to combustion processes.
