I’m buying the books for my thermodynamics course. The required text is Reeds Vol 3. There’s also an optional text called Applied Thermodynamics For Engineering Technologists by Eastop and McConkey. Its not a really really expensive book. Has anyone looked at it? Is it worth getting, or is Reeds good enough?
Hi Emrobu,
Hope all is well. This link is for the optional textbook you spoke about it’s free. You might have to scroll slowly because it’s 593 pages. I hope this helps. Please keep us posted when you start different sections of your class. I would like to study along with you on my own. If you look at the table contents, there is plenty to discuss and learn. Have they provided you a course outline?
If you can understand thermodynamics concepts and theory without the math, you’ll have a much better grasp of it. Then add the math. Too many people teach thermo with only math, not concepts.
Just for the record: I’m not providing free online tutoring for people who are paid to post on forums or have a whimsical passing interest in math-intensive technical subjects, or who really need a friend or what-ever the deal is. I support myself and my studies by working nights and I’m in a classroom for 30 hours a week. I don’t have the time, I’m not charitable enough, and I’m not interested in hand-holding tar-babies.

Hi Embrobu - Good luck with your class. I hope the link to the book you asked about helps you out. Sounds like your just getting started. Been there done that years ago. Keep a positive attitude.

Emrobu - Keep me posted if they talk about partition function’s in your class.
Some folks just don’t get it. . . .
0th law: self explanitory
1st law: what goes in, must come out (energy conservation)
2nd law: heat flows from hot to cold (just like water flows downhill)
3rd law: at absolute zero, shit stops
You are now an expert.

The new edition of Reeds (5th, 2016) has a lot of errors. If you need this text try to get the 4th edition (1996), which doesn’t. Here is the list of corrections I have found so far. Next year when I have this topic again, I will update the list.

And, so far as I’ve found, the only thing that the new edition has that the old edition lacks is a half-assed description of the Miller Cycle.
