Powerpoints, homework and supplementary material will be posted. Required Text: Çengel YA, Boles MA. Thermodynamics. 8 th Edition. ISBN-13: Older editions are acceptable for material. Learning Objectives: 1. Determine whether a real system should be modeled as closed or open. 2. Explain basic concepts of thermodynamics such as system, state, state postulate, equilibrium, processes and cycles.

2 3. Differentiate between intensive and extensive properties. 4. Use thermodynamic charts and tables to find values of intensive properties for systems in specified states. Intensive properties include temperature, pressure, specific volume, internal energy, enthalpy and entropy. 5. Use P-V-T surfaces to visualize a thermodynamic process. 6. Differentiate between forms of energy that cross the system boundary (work, heat and flow energy) versus forms of energy of the system (internal energy, kinetic energy, potential energy). 7. Execute a first law analysis of a closed or open system undergoing a process. 8. Mathematically and conceptually describe adiabatic, isothermal, isobaric, isometric, and isentropic gas law processes including state locations, heat transfers and energy changes. 9. Model open system devices such as nozzles, diffusers, heat exchangers, pumps, compressors, turbines, boilers, and throttling valves. 10. Describe the Kelvin-Planck and Clausius statements of the second law of thermodynamics. 11. Analyze simple power and refrigeration cycles including the Carnot, Otto, Diesel, Brayton and Rankine cycles. Expectations: 1. Lectures: Students are expected to attend all classes. In the classroom, lectures will be given on the course material. Background reading in the book should be read before class. Lectures will present fundamental theories and concepts that will be utilized throughout the course. They will provide the basis for future lectures. In lecture, material that will be on the homework and tests will be covered extensively. Examples that are similar to what is seen in homework will be done. Tests will also be given in lecture. 2. Outside of class: Students need to spend time outside of class as well in order to do well in this class. For every 1 hour of class, students should spend on average up to 2 hours outside of class. Before class, students should read the sections that will be covered to familiarize him/herself with the material. 3. Office Hours: If one finds him/herself struggling, PLEASE COME ASK FOR HELP!!! I will hold office hours (see above). Students should come to office hours for help with problems or concepts explained in class. Please come to office hours prepared and at least have attempted the problems. Other resources are available at the tutoring center. 4. Homework and Tests: In all graded work, explain your train of thought by writing clearly, orderly and legibly. All steps needed to solve a problem must be written out. No points will be given for the correct answer but no work. It is also easier to give partial credit if all steps are written even if the final answer is incorrect. 5. Study Groups: Students are encouraged to form study groups and work together on homework problems. However, every student is required to turn in his/her own work. Blatant copying will result in a score 0 for the assignment. Collaborative learning is great for helping students who are struggling with the material. It also helps students who are performing well to better understand the material by having to explain it to another student. The best way to learn something is to teach. Frank Oppenheimer. 6. Late work: All late work without a valid excuse is a 0 on that assignment. Evaluation: 1. Attendance and Participation Students are expected to attend all lectures and participate in exercises. We will go over many of the book examples during the lecture. Problems will be given that are relevant to concepts taught in class that day. This is to ensure class attendance and also promote collaborative learning. Exercises may be turned in. 2. Quizzes Low-stakes quizzes will also be intermittently given. You will get at least 1 weeks notice. 3. Tests Tests will be given every few weeks to assess your progress in the course. They will cover material after the previous test to the test date. 4. Homework Homework will be assigned almost weekly on Friday. Assignments will be due the next Friday at the end of class. More details below. 5. Comprehensive Final

3 The final will cover the whole quarter with an emphasis on material not tested. The final is scheduled for Friday, June 17 th from 9AM-11AM. Course Grading: Quizzes (3) 15% Tests (3) 45% Homework 15% Final Exam 25% Homework Guidelines: Each student must submit his/her own work. No credit will be given for no work. Not all problems will be graded. 1. Homework must be done on engineering graph paper or white computer paper. No lined paper. a. If using engineering graph paper, only write on one side. Side with lighter lines. 2. Presentation is considered in grading. Space problems out. 3. Include a sketch of problem and follow procedure to solve problem. 4. Circle the final answer. Report to 3 significant digits. Include units. 5. Please staple all sheets together. Quizzes, Tests and Final Guidelines: Just as in homework, all work must be shown for full credit. An equation sheet will be provided. Must bring a scientific calculator and writing utensil. Code of Academic Conduct: The student is in the unique position of being a member of the community at large, having the rights and responsibilities of any citizen, and of being a member of the college community.
