Course description
Course aim
The aim of the course is to teach students to:
Formulate and apply the thermodynamics laws in engineering practice,
Formulate and quantitatively estimate power/refrigeration cycles (energy balance),
Understand thermodynamic processes of a humid air mixtures,
Qualitatively estimate energy effect of chemical reactions,
Present calculations in a professional, neat, and orderly manner that can be understood
and evaluated by others knowledgeable in the field of thermodynamics,
Make basic measurements in thermodynamic systems and prepare professional reports
with particular emphasis on the process description and data analysis,
Team working during the laboratory demonstrations.
The course outcomes meet the ABET requirements specified in the Criterion 3 in points a, b, c,
e, f, g, h and k.
Course
coverage
The course is split into two parts. The first part introduces the properties of pure substances,
the first and second thermodynamics laws, and thermodynamic definitions of entropy and
exergy terms. The second part focuses on power and refrigeration cycles. In addition, basic
information about chemical reactions (combustion) will be discussed. All together combined
will allow future engineers to perform energy analysis of engineering systems.

Course form
Lectures and
recitations
Lectures will be given three times a week. Besides theoretical
presentations, part of classes will be conducted in recitation
form.
Homework
Since the course does not have separated recitation session,
homework problems are a very important component of the
learning process. Students are encouraged to attend office
hours of the Instructor to discuss elaborated material.
Lab
demonstrations
To clarify discussed problems, thermodynamic analyses of four
real engineering applications will be conducted: (i) overall
efficiency of compressed air system (UW Oshkosh Integrated
Industrial Energy Lab), (ii) operation of industrial chiller (IIEL),
(iii) co-generation system (UW Oshkosh bio-digester)
(iV) energy balance for a steam boiler (UW Oshkosh Heating
Plant).
General rules
Attendance
While there is no formal requirement, attendance in lectures is highly recommended.
Thermodynamics is fundamental and probably one of the most difficult courses in
Mechanical Engineering Technology program. To make discussed material more intuitive,
related physical phenomena will be presented during lectures. Earning high grade, without
regular class attendance, will be difficult, if not impossible. During each lecture, attendance
list will be taken for my own information. Bonus points (5% of a final grade) will be awarded
to those students, who miss no more than one scheduled class period for any reason.
Classroom
courtesy
Please turn off all cell phones before class and keep them away for the entire class period.
Every using of any type of electronic equipment, not involved directly in a teaching process
(smart phones, mp3 players, laptops, etc.) will cause deduction of 1% from a final grade
each noted time.
It is not recommended to use laptops during lectures except exercises for which its usage
will be predicted. Laptops, having many distractors (internet, communicators, games, etc.)
are not very good for taking notes.
Academic
dishonesty
Academic dishonesty of any sort will not be tolerated. The giving or receiving of assistance
on any exam or the misrepresentation of someone else’s work as own is considered as a
cheating. Plagiarism on written assignments is unacceptable. Students may work together
on projects, but returned homework should be personally authored. All cheating offenses
will be reported to the Dean of Students Office. Zero points for assignment is predicted as a
minimum sanction for dishonesty. However, depending on the nature of the offense,
cheating may cause recommendation in failing grade in the class or expulsion from the
University. Please refer to the UWO Student Code of Conduct for additional information.
Office hours
I am willing to help any student who is having difficulty in material understanding. I am most
willing to help hard working students, who can demonstrate background concept revision,
own studied notes and lab demonstration materials. Before coming out of my office hours,
please confirm appointment by e-mail.

Grading scale
Examinations
There will be tests. Both of them are closed-book and closed-notes events, but a sheet with
self-written equations will be allowed. In addition to solving math problems, students may
also be asked to provide short written answers to questions related to the theory being
covered.
Homework
Frequency
Typically, one homework set will be assigned every week. Unless otherwise announced, a
homework set will be assigned each Monday, and it will be collected at the beginning of
class on the following Monday. Homework sets that are not submitted during class on the
scheduled due date but are turned in by the end of the next class will receive 50% credit.
Homework assignments turned in later than this will not be graded.
General rules
Students are encouraged to form “study groups” if that helps them. However, students are
responsible for completing and submitting own assignment. Copying the work of another
student (even within the same study group) will be considered as violation. Homework will
be composed of few simple problems to solve or to describe a demonstration experiment.
Specifications for
homework
submissions
It is important to do engineering calculations accurately using the correct concepts and
logic. However, the presentation of engineering calculations is also important. In
engineering practice, someone reviewing presented calculations must be able to read your
writing and understand a logic. For this reason, a homework will be scrutinized on two
criteria: correct application of theory and engineering principles, and neatness and quality of
presentation. So, homework should be or have:
Written on a standard letter size paper (no paper from spiral bound notebooks)
Presented as legibly as it is possible, with clearly indicated the final answer
Named and page-numbered (with total numbers of pages x of y) on every page
Stapled in case of multipage work
Adequate written comments and list of made assumptions
Units shown for all numbers substituted into equations and for final answers.
Additional tips
The answers for many problems are in the back of the book. Writing down the correct
answer from the back of the book when a solution does not support it, is not the best idea.
Partial credit will be awarded for incorrect solutions if some of your logic is correct.
The purpose of the homework is to help to learn the material covered in the lectures and
discussed in the textbook. For that reason, the grading of the homework will probably be
more lenient than the grading of exams.
