1st Semester of A.Y. 2016-2017. WFUV : ME 4 WF 10:00 –12:30 | WFWX : ME 4 WF 13:00 –15:30.
course description and objectives This is an introductory course on engineering thermodynamics for mechanical engineering majors. The primary objective of this course is to foster appreciation of the nature of energy and its manipulation, as well as the nature of impossibilities. Students are expected to focus on learning rather than grades. After all, they are honorable and excellent students, and definitely not sly capitalists. This course aims to: · · · ·
Provide students with a thorough understanding of fundamental concepts in thermodynamics. Provide students with the ability to identify and analyze basic thermodynamic systems, processes, and cycles. Provide students with experiences, group or individual, of solving problems systematically. Ensure that students are ready for solving a wide range of practical problems directly involving thermodynamics.
learning outcomes After the course, the student should be able to: · · · ·
Frame anything in the context of thermodynamics. Systematically solve engineering problems involving direct applications of thermodynamics. Explain to children what (1) thermal equilibrium, (2) energy conservation, and (3) irreversibility are. Define and describe energy in its archetypal forms, identify energy pathways, and assess feasibilities in the context of thermodynamics. · Analyze thermodynamic systems, processes, and cycles. · Describe and analyze basic power, refrigeration, and heat pump cycles.
requirements and expectations · Readings. 32 half-sequences at 0% each. Students are expected to read assigned readings before corresponding lectures start. · Seatworks. 32 half-instances at 0.5% each. Students are expected to be present during seatworks which is every meeting. · Midterm exams. 3 instances at 16% each. Each exam is out of 100 and score should not go below 40. · Final exam. 1 instance at 36%. The final exam is out of 100 and score should not go below 40.
