Engineering Sciences 25 — INTRODUCTION TO THERMODYNAMICS Catalogue Description: The fundamental concepts and methods of thermodynamics are developed around the first and second laws. The distinctions between heat, work, and energy are emphasized. Common processes for generating work, heat, or refrigeration or changing the physical or chemical state of materials are analyzed. The use of thermodynamic data and auxiliary functions such as entropy, enthalpy, and free energy are integrated into the analysis. The numerous problems show how theoretical energy requirements and the limitations on feasible processes can be estimated. Prerequisites: Math 13, Physics 13, Engs 20 or Cosc 1 & 10. Learning objectives: Provide a substantive exposure to: 1. Key thermodynamic concepts such as heat, work, energy, power, enthalpy, entropy, and exergy. 2. An understanding of physical properties, relationships between them, and where to find data. 3. Engineering analysis based on the first and second laws of thermodynamics in combination with key thermodynamic concepts and physical property data. 4. Common cycles for generating work, heat, or refrigeration, their components (e.g. compressors, turbines, heat exchangers), and evaluation of potential and actual efficiencies. 5. Gain an appreciation for application of thermodynamics to chemical and biological systems. 6. Observation of recorded laboratory exercises that demonstrate key concepts and give students an opportunity to analyze laboratory data. Instructors: Professor Lee Lynd.

Schedule: MWF 2:10 – 3:15 PM, X-hour Th 1:20 – 2:10. Class lectures via Zoom. I understand that Thayer Computing will communicate with you regarding access. As presented in detail in the course schedule included with this syllabus, lectures will be on Monday, Wednesday, and Friday. The X-hour will be used most weeks, in part to allow for the likelihood that we may proceed a bit more slowly because of the remote format for the class. Help sessions will be held during the two days prior days on which homework is due at various times to accommodate students in different time zones. Text:

Moran, M.J., H.N. Shapiro, D.D. Boettner, M.B. Bailey. Fundamentals of Engineering Thermodynamics. 8th edition. Wiley. 2014. We will follow the text closely, and I expect students to have access to the text for homework and exams. This text is widely used to teach undergraduate thermodynamics, and students from past course offerings have found it useful to learn from. The order in which we consider topics will deviate somewhat from that in the text, to be made clear as the class proceeds. The Moran et al. book is written from a mechanical (e.g. as opposed to chemical, materials, or biological) perspective, exclusively on a macroscopic (rather than microscopic, quantum) perspective, and it focuses primarily on older energy technologies. I will make an effort to bring to class some topics that are not addressed in the Moran et al. text. Biological and chemical applications of thermodynamics will be supported based primarily on class notes.

Communication: The course syllabus, powerpoint files and other materials presented in lecture, homework assignments and solutions and exam solutions will be posted on Canvas . Lectures will be recorded, although class attendance is encouraged. Homework: Six homework assignments will be due on Fridays and one the last day of class as indicated on the schedule. Homework will be assigned each week, and solutions will be posted. Assignments must be turned in before class on the due date. Graders will make every effort to grade your homework quickly and correctly. For homework help sessions, TA’s are instructed not to provide you with answers to the homework or to “check” your answers. Their role is to help you develop and understand a systematic approach to problem solving. Please adhere to the following homework guidelines: • Problem sets that are late (30 seconds to 24 hours) will be given a 25% deduction. Problem sets later than 24 hours will not be accepted. In cases of illness or family emergencies, I have the option to not count a particular homework assignment in computing the final grade. • Homework should be submitted electronically. Protocols will probably be revised based on experience, but at this time please plan on submitingt each homework problem to Canvas as a separate PDF. • Please record your NAME, COURSE NUMBER, ASSIGNMENT NUMBER, AND PROBLEM NUMBER at the top of the file for each problem. • Homework assignments can be typed or hand-written and then scanned. Please write neatly and provide enough detail that the grader can follow your work. When appropriate, units are required for numerical answers. Draw a box around final answers. If the grader cannot follow your work, you will not receive full credit for the problem. • Graded problem sets will be returned electronically. Cour sei nf or mat i on

Labs:

Four labs will be conducted during the term. The lab deliverables will be included in, and graded as part of, the homework assignment. The format will be: Watch a prelab recorded video and answer brief concept questions; participate in a lab “meeting” on Tuesdays (different times to accommodate various time zones) for demo experiments and small group discussions; then with data provided to you complete analysis to be submitted with the weekly homework.

Exams:

We will have three one hour exams as noted in the schedule. These will be open book and open notes. Students will be expected to have a calculator. I do not expect the exam dates to change.

Final:

There will be a 3-hour final. At this time it is scheduled for Friday, June 5 at 11:30 AM, although that may change. The exam will be cumulative but with more weight given to material introduced at the end of the course. As for the exams during the term, the final will be open book and open notes and students should bring a calculator.

Grading: Grades for this edition of Engs 25 will be recorded on student’s transcripts as Credit or No Credit. Citations for outstanding performance will also be recorded. In order to provide feedback to students, I will assign unofficial grades according to Dartmouth’s scholarship rating scale (http://www.dartmouth.edu/~reg/transcript/grade_descriptions.html): A: Excellent mastery B: Good mastery C: Acceptable mastery D: Deficient mastery E: Seriously deficient mastery I feel no obligation to have the distribution of grades conform to some preconceived target. All students who achieve a weighted average score of 90 or above will receive a grade of at least A-. The contribution of class assignments to the final grade will be as follows: Homework: 20% Mid-term exams: 13% each for a total of 39% Lab exercises: 15% Final: 26%

Remote Format Adjustments and Accommodations We are all in uncharted territory with respect to both the situation at large as well as proceeding with learning and teaching in a remote format. Adjustments may well be required as we go in response to circumstances outside the classroom, and in response to what we learn as I, and many of you, experience remote offering of a Dartmouth course for the first time. I invite and value any input you offer about what is and is not working, and I thank you in advance for your patience and flexibility. I will do my best to make the 2020 edition of Engs 25 a high quality experience for all students, and I am optimistic that this will be achieved. Out-of-class disruptions. Events resulting from the COVID-19 pandemic have the potential to prevent you from continuing to participate in the class, for example due to contraction of the disease by you or a loved one, increased familial responsibilities, financial difficulties, or impacts on your mental/emotional health. In the event that you are directly or indirectly impacted by COVID-19 in such a way that will affect your participation in the course, let me and the undergraduate dean for your class know. Our first priority is your health and security. We will work to put you in touch with appropriate resources to assist you. However, we cannot assist you if we don’t know there is a problem. Remote access. I expect students to be able to access lectures and homework help sessions on line via Zoom. If this presents a problem for you, please let me know. Consent to record. By enrollment in this course, it is understood that students agree to the following: 1) Consent to recording of course and group office hours a) I affirm my understanding that this course and any associated group meetings involving students and the instructor, including but not limited to scheduled and ad hoc office hours and other consultations, may be recorded within any digital platform used to offer remote instruction for this course b) I further affirm that the instructor owns the copyright to their instructional materials, of which these recordings constitute a part, and distribution of any of these recordings in whole or in part without prior written consent of the instructor may be subject to discipline by Dartmouth up to and including expulsion; b) I authorize Dartmouth and anyone acting on behalf of Dartmouth to record my participation and appearance in any medium, and to use my name, likeness, and voice in connection with such recording; and c) I authorize Dartmouth and anyone acting on behalf of Dartmouth to use, reproduce, or distribute such recording without restrictions or limitation for any educational purpose deemed appropriate by Dartmouth and anyone acting on behalf of Dartmouth. (2) Requirement of consent to one-on-one recordings I hereby affirm that I will not under any circumstance make a recording in any medium of any one-onone meeting with the instructor without obtaining the prior written consent of all those participating, and I understand that if I violate this prohibition, I will be subject to discipline by Dartmouth up to and including expulsion, as well as any other civil or criminal penalties under applicable

Disabilities “Students requesting disability-related accommodations and services for this course are encouraged to schedule a phone/video meeting with me as early in the term as possible. This conversation will help to establish what supports are built into my online course. In order for accommodations to be authorized, students are required to consult with Student Accessibility Services (SAS; [email protected]; SAS website; 603-646-9900) and to email me their SAS accommodation form. We will then work together with SAS if accommodations need to be modified based on the online learning environment. If students have questions about whether they are eligible for accommodations, they should contact the SAS office. All inquiries and discussions will remain confidential.”

Honor Principle The Honor Principle (https://student-affairs.dartmouth.edu/policy/academic-honor-principle) is an integral part of your education at Dartmouth and in this course. In general: The Faculty of Dartmouth College, in recognizing the responsibility of students for their own education, assumes intellectual honesty and integrity in the performance of academic assignments, both in the classroom and outside. Each student upon enrollment at Dartmouth College accepts this responsibility with the understanding that any student who submits work which is not his or her own violates the purpose of the College and is subject to disciplinary actions, up to and including suspension and separation. Acknowledge, by means of footnotes, all sources of help or information outside of the text and sources introduced in class. Failure to do so constitutes plagiarism and violates the Honor Principle. It is not permitted to receive aid or information from anyone but the professor on an exam, nor is it permissible to give aid or information to a classmate on an exam. The Honor Principle extends in the obvious way to library reserve books, computer resources, and other facilities associated with the course. To hoard, “borrow” without authorization, damage, or in any other way restrict the access of your fellow students to these public resources is clearly in violation of the spirit of the Honor Principle. Specifically, in this section of Engs 25: Homework. The primary objective of the homework is to learn the material, with evaluation a secondary objective. Experience as well as educational research strongly indicate that people learn best when they work together, and learn even more when they explain the course material to each other. Accordingly, you are encouraged to collaborate on homework, within certain limits. You must however list the names of all persons with whom you collaborate on homework assignments. Though you may work together, when you turn in a paper with your name on it you are saying to me that the final work is yours and that you understand your solution and can explain it to me. Copying other people’s answers or failing to cite your study partners misrepresents the work of others as your own. This is a violation of the Honor Principle and can have serious consequences. It is also a poor way to learn. You should not assume that this approach to homework necessarily applies to other courses. Exams. Preparing for an exam is one of the most important learning experiences in this course, which I encourage you to make the most of. Exams are also the primary means of evaluation in the course, determining 65% of your grade. All work on exams is to be your own.
