Course learning outcomes By the end of this course, the students will be able to: 1. Define units of pressure, temperature, density, mass, and moles, SI and English system, and use conversions. 2. Use thermodynamic tables and diagrams and apply equations of state, such as the Ideal Gas Law. 3. Understand the difference between steady-state and transient processes, open and closed systems. 4. Describe the meaning of specific volume, enthalpy, and internal energy, and how to obtain them from thermodynamic tables and diagrams. 5. Identify the difference between heat and work, isentropic and isenthalpic processes. 6. Apply mass and energy balances (First Law) to a variety of processes and circumstances. 7. Define the meaning of isentropic processes: obtain entropy from thermodynamic tables and diagrams. 8. Define the meaning of efficiencies in turbines, compressors, and pumps, and use them to solve problems. 9. Obtain changes in internal energy, enthalpy, and entropy by using equations, tables, diagrams, and fundamental properties, such as C p and C v. 10. Identify power and refrigeration cycles and calculate their efficiencies. Method of Evaluation: Mid-semester exams 55% Final 30% Homework 10% (approximately weekly) Instructor Discretion 5% (class participation, etc) Teaching Assistant: Yu-Wen Huang yuwen@tamu.edu Office hours/discussion: Monday 2-3 pm Tuesday 5-6 pm Final Exam: Closed-book.

Course Policy: 1. Course Web Page. All course related information such as problem sets and their solutions will be available on the course website at: vnet.tamu.edu Problem Sets. Homework assignments will be announced on the course web site. Completed problem sets are to be turned in at the beginning of the Lecture on the date it is due. Joint discussion of problem solutions is acceptable, however, copying is not (plagiarism!). Late problem sets will not be accepted, and missed problem sets will receive a grade of zero. 2. Mid-semester Exams. Unexcused mid-semester exams will receive a grade of zero. Permission for makeup exams must be approved by Professor Chen and will be given only in case of an emergency verified by note from the emergency dean. You must notify Professor Chen within 24 hours of the scheduled exam period, and you must provide a signed, written letter on official letterhead stationery from the emergency dean justifying your absence. This must be provided prior to the makeup exam. Professor Chen reserves the right to not give a make-up exam but to use instead the average of the student s other in-class exams adjusted relative to the class averages. 3. Exam Regrades. After the exams are returned, all students will have until the beginning of the second lecture following the day the exam was returned to provide written appeal of the exam score. Exam regrades will involve a regarding of the entire problem in question. If a request is made for more than one problem, the entire exam will be regarded. Page 3 of 5 Printed: 2/4/09

Scholastic Dishonesty: As commonly defined, plagiarism consists of passing off one s own the ideas, work, writings, etc., which belong to another. In accordance with this definition, you are committing plagiarism if you copy the work of another person and turn it in as your own, even if you should have the permission of that person. Plagiarism is one of the worst academic sins, for the plagiarist destroys the trust among colleagues without which research cannot be safely communicated. If you have questions regarding plagiarism, please consult the latest issue of the Texas A&M University Student Rules, under the section Scholastic Dishonesty. Page 4 of 5 Printed: 2/4/09
