2 Course Information Basic Information Required or elective Course Credit (Hours/ECTS credits) Required (3-0-0/6) Class Hours and Classrooms Tuesday 12:00-12:50 A226 Friday 14:00-15:50 A226 Level of Course Instructor Sophomore Dr. Özgür Uğraş BARAN ( Room: G220 Office Hours Tuesday 09:00-10:30 Friday 11:00-12:00 or by appointment Textbook Principles of Engineering Thermodynamics 8th edition. Moran, Shapiro, et.al. John Wiley and Sons Course Description The thermodynamic system and properties, thermodynamic processes; work and heat interactions. The First Law for systems and for flow processes; the Second Law and entropy. Irreversibility and availability. Objectives Thermodynamics is the branch of science and engineering that aims to gain fundamental understanding about the heat temperature and also energy and work. Thermodynamics is the fundamental branch to achieve engineering designs in power generation, heating/ cooling, transportation/ propulsion etc. This course is an introductory level course to understand thermo-physical properties of substances and introduce thermodynamics laws in system and control volumes. Energy and work relations is also considered. 2

3 Course Learning Outcomes Upon successful completion of this course, a student will be able to 1. Understand and use the concept of system, 2. Evaluate Thermo physical properties of substances, 3. perform basic comprehension on several forms of work energy and heat and evaluate thermodynamic systems, 4. Apply conservation of energy for the control mass and control volume processes, 5. Understand second law of thermodynamics and irreversibility's and how to predict correct direction of physical processes. Course Plan and Policies The course schedule is tentative and it will be adapted to the pace of the class. There will be three midterm exams. Midterm weeks are given in the tentative schedule and they are subject to change. Date for the final exam will be announced at the end of the semester. The final exam will cover all topics. Make-up exams will be given only for medical excuses documented by medical reports that are approved by the Student Health Center of TEDU or other documented excuses approved by executive branches to TEDU. All make-up exams will be given after the final exam. The dates for Make-up exams for Finals are decided by Make-up Exam Commission according to the rules and regulation of TEDU. Please see the link You may use a scientific calculator during the exams. Programming the calculator before or during the exams are not allowed. You are not allowed to use cell phones during the exams. You are expected to attend on all classes. Classes start on the hour. Please be respectful to your class mates by being on time. Cell phones should be turned off and kept out of sight during the classes. You are not also allowed to use your computers/ tablets etc. at the classroom. Homework Policy There will be 5 to 7 homework during the semester. All homework are paper based. You are supposed to submit all homework. Late submission is not allowed. You loose 20/100 points for each day you deliver your homework late. Grading method given below is 3

4 tentative, but note that there will be no reduction on the percentage of the homework. Therefore, please take it seriously Some homework will contain preparatory material for the next lecture. For a fruitful course, please be on time.

7 ETHICS Plagiarism All of the following are considered plagiarism: Turning in someone else's work as your own Copying words or ideas from someone else without giving credit Failing to put a quotation in quotation marks Giving incorrect information about the source of a quotation Changing words but copying the sentence structure of a source without giving credit Copying so many words or ideas from a source that it makes up the majority of your work, whether you give credit or not" ( Plagiarism is a very serious offense and will be penalized accordingly by the university disciplinary committee. The best way to avoid accidentally plagiarizing is to work on your own before you ask for the help of other resources. Cheating Cheating has a very broad description which can be summarized as "acting dishonestly". Some of the things that can be considered as cheating are the following: copying answers on exams, homework and lab works, using prohibited material on exams, lying to gain any type of advantage in class, providing false, modified or forged data in a report, plagiarizing, modifying graded material to be re-graded, causing harm to colleagues by distributing false information about an exam, homework or lab. Cheating is a very serious offense and will be penalized accordingly by the university disciplinary committee.
