ISBN 13 978-0471-78735-8 Instructional Objectives Engines are used to convert thermal energy into mechanical work. Engineers are professionally trained personnel who have the know-how of operating engines. Thermodynamics is the very study that provides the knowledge and the principles that govern the transformation of energies between different forms (heat or work) and in different parts of the engine. After completing this course, students should be able to do the following: Make engines cycle calculations, with regard to their operating conditions and efficiency. Determine the amount of work produced and the temperature, pressure conditions. Use equation of state to determine the working fluid properties. Understand and implement enthalpy, heat capacity and vapor pressures in efficiency estimation. Learn how a refrigeration cycle works, including absorption refrigeration. Calculate using property correlations, such as velocity of sound, heat of vaporization, Joule-Thomson coefficient, compression ratio, and coefficient of performance. Calculate inlet and outlet conditions for equipment such as throttles, nozzles, and steam turbines. Master the types of engine cycles such as Rankine Cycle, Brayton cycle, Otto cycle, and Carnot cycle. GRADE: No make-up exams. Homework must be done online (WileyPlus). No late Homeworks!

(10) Academic Integrity As noted in the University Catalog: “All forms of academic dishonest at Cal Poly Pomona are a violation of university policy and will be considered a serious offence.” For this course “academic honesty includes but is not limited to: Plagiarism…, Cheating During Exams… and Use of Unauthorized Study Aids…” As a student in this class it is assumed that you maintain academic integrity and honesty. Cheating can result in a grade of F in this class, or worse! So don’t do it.
