Engineering Thermodynamics

[Gabby Dreher]

Thisbook deals with Engineering Thermodynamics, where concepts of thermodynamics are used to solve engineering problems.Engineers use thermodynamics to calculate the fuel efficiency of engines, and to find ways to make more efficient systems, be they rockets, refineries, or nuclear reactors.One aspect of "engineering" in the title is that a lot of the data used is empirical (e.g. steam tables), since you won't find clean algebraic equations of state for many common working substances.Thermodynamics is the science that deals with transfer of heat and work.Engineering thermodynamics develops the theory and techniques required to use empirical thermodynamic data effectively.

This course forms the foundation for the Heat Transfer course, where the rate and mechanisms of transmission of energy in the form of heat is studied. The concepts can be used in further study including internal combustion engines, refrigeration and air conditioning, and turbomachines to name a few.

Rigorous treatment of the molecular basis will be omitted, in favor of formulations most useful for developing intuition and understanding common technologies. Students of physics will want to pair this text with one on Statistical Mechanics.

The text builds outward from the basic concepts and definitions of the underlying physics, guiding the reader through thermodynamic properties and introducing the subject of gasses. From there, the First and Second Laws of Thermodynamics are...read more

The content of the subject of Classical Thermodynamics has, since the science developed, has, in its most basic level, not been subject to change, and, at the level of this text, is unlikely to ever change.

The text is generally clear and easy to follow; the prose is accessible for any reader. As mentioned above, under Comprehensiveness, the Solutions for the Examples might need to be revisited with the view of making the steps, and their logic, more accessible to the student.

The Sections of each Chapter are formatted according to a consistent framework. The terminology, once defined, is used consistently. A Glossary is available for the user to check definitions of terms.

In using this book in a course, it would be fairly easy to define Reading and Problem assignments from specific Sections. Under the Chapter headings, there are Sections that are arranged in a logical and sequential order. The Sections contain text, followed by examples which are, in turn, followed by an external link to a website that contains Practice Problems. It should be fairly easy to assign the Sections in an Academic Calendar.

The Left Menu provides for easy navigation from one region of the book to any other region.

There was a large amount of white space throughout the book. For example, Chapter 3. Ideal and Real Gasses began on p. 80 with only the title at the top of the page; the following page was blank. The text of the Chapter began with the first Section on p. 82.

The Appendices were the place where the Tables of Thermodynamic values were to be found. Some Tables, as in Appendix A, were long enough to spread over a number of pages. The students would then have had to retrieve values from these tables; they would have been inconvenienced by the absence of the column headings on each page; the headings were only to be found at the top of the first page.

Some Tables, as, for example, Table B1: Saturated Ammonia, had its sixth and perhaps other columns terminated at the right edge of the page in the pdf display; only 2 digits of the values there were visible.

The book is most suitable for a one-term, introductory engineering thermodynamics course at the undergraduate level. It may also be used for self-learning of fundamental concepts of classical thermodynamics.

Engineering Thermodynamics forms a fundamental pillar in the engineering disciplines. This field deals with energy and its transformations. You get to understand how to harness and utilise different forms of energy efficiently.

Engineering Thermodynamics is an aspect of engineering science that studies energy, its conversion among different forms, the ability to perform work, and the properties of the substances involved in these processes.

Given its significance, you'll find the principles of Engineering Thermodynamics applied almost everywhere. It plays a crucial role in many branches of engineering and affects our everyday lives in countless ways.

As seen above, Engineering Thermodynamics has a massive range of applications. It's a driving force behind innovations from renewable energy solutions such as solar panels and wind turbines, to the vehicles you use to commute and gadgets that entertain and educate you!

For instance, in Mechanical Engineering, when dealing with car engines, the principles of thermodynamics explain essential processes like how fuel's combustion drives the vehicle. Here, the energy from fuel is converted into heat in a closed system before it becomes mechanical work.

Remember, operation of a system in complete harmony with the laws of thermodynamics determines its effectiveness, lifespan, and safety. Understanding and applying thermodynamics principles duly ensures higher efficiency and safety of systems and processes.

Concepts and principles may seem abstract without relatable examples. Through exploring both simple and complex examples, you'll gain a more vivid apprehension of Engineering Thermodynamics and its application in engineering problems.

The first example highlights the conversion of work into heat. Here, imagine you're rubbing your hands together on a cold day. Friction between your hands generates heat, a sign of energy transformation from work (rubbing hands) to heat, well explained by the first law of thermodynamics. This law states that energy cannot be created or destroyed; it merely changes forms: \( \Delta U = Q - W \), where \( \Delta U \) is the change in internal energy, \( Q \) is the heat added to the system, and \( W \) is the work done by the system.
