TL;DR Don't print these for your exams and hope for the best.
I have spent hundreds of hours auditing these equation sheets as a graduate student, but it is likely there are some mistakes, typos, omissions, misunderstandings, and so on. I correct errors as I find them. Ultimately, these should be thought of as personal notes and not authoritative compendia.
The goals of these equation sheets are to:
They are not intended to be fully self-explanatory; use of textbooks and course materials will provide context and demonstrate usage. Neither are they meant to be complete or comprehensive for any subject; they are based on what was presented in class.
The textbooks from which material is derived are included in the References sections. In general, the equations follow the order in which they appeared in classes and in the textbooks. For material from academic journals, the DOIs are listed. Some equations are taken from Wikipedia, LibreTexts.org, and other online sources. In general, they can be found by searching for the descriptions of the variables involved or for the subject. Some materials from lecture notes or my notebooks do not have primary sources; in these situations, I have performed dimensional analysis as well as omitted equations which lacked supporting examples. I can provide page numbers or equation numbers for textbook material and URLs of online sources upon request.
I have provided some handwritten notes which I think are valuable as examples and visual references. I have also included or linked useful material and online tools that I utilized.
In particular, ECH 252 and ECH 259 are often my best guesses as it seems every source I references had considerably different formulations and notations from the others, and I lack the expertise and time to rectify this.
The content of this site is based on my undergraduate education at Michigan Technological University and my graduate education at University of California - Davis.
During my sophomore year, the inconsistencies between and within classes necessitated the development of chemical engineering equation sheets, the design of which was inspired by those of the MTU Physics Learning Center. Another motivating factor was that we were allowed to make our own and use them on exams.
My intensely interdisciplinary studies required that notation work across chemical, electrical, mechanical, and materials engineering. This resulted in much refactoring, which I think was mostly improvements. Notably, my mass transfer variables deviate from those of Bird, Stewart, and Lightfoot, as I thought the choices of BSL to be arbitrary and confusing. BSL versions of my equation sheets exist and can be provided upon request; I might upload them here eventually.
If you find an error, please investigate it and let me know why you think it is incorrect, keeping in mind TMTOWTDI: There's More Than One Way To Do It. Please provide any relevant sources.
Note that I probably don't have time to explain how I formatted things in LaTeX. I'd like to learn more aspects of electrical and mechanical engineering, and if I do so, I will build equation sheets and upload them. Do note that notation can sometimes change, but at this time, I think changes will be minimal.
I don't want to maintain a public repository of LaTeX code, but can provide it upon request.
