I.  TEXT

Yunus A. Cengel and Michael A. Boles, Thermodynamics, An Engineering Approach, 5th Edition, McGraw Hill, 2006, or any other older editions.

               

 

II. COURSE DESCRIPTION

This course provides an introduction to the fundamental principles of thermodynamics and their application to engineering systems, particularly energy conversion devices such as power plants, refrigerators, and engines.  This course will emphasize thermodynamics’ properties of pure substances in solids, liquids, and gaseous phases as well as the first and second law of thermodynamics.

 

 

III. COURSE OBJECTIVES

  1. Learn the principles of the conservation of mass and energy and second law of thermodynamics through applications to simple closed and open systems and engineering devices such as pumps, turbines, nozzles, diffusers, and heat exchangers.
  2. Learn the basics of cycle analysis for vapor and gas power and refrigeration cycles.
  3. Learn the process of problem solving.
  4. Learn to conduct the basic analysis for the design of a process or a simple system.

 

IV. COURSE CONDUCT

This course will provide you with a variety of opportunities for mastering the concept of the course.  These include: textbook, lectures, homework problems, quizzes, exams and the design project.  Weekly homework assignments and solutions are posted at www.csun.edu/~sdijulio/ME370/Homework.  Students should solve all weekly assigned problems and then refer to the solutions to gain maximum benefit.  Additional problems will be solved in class to help you master the course material.

 

The assignments will be weighted approximately as follows:

               

                Design Team Project                                           10%

                Three quizzes (each 5%)                     15%

                Two Mid-term Exams (each 22.5%)  45%

                Final Exam                                                             30%

No late projects will be accepted.  There will be no make up quizzes or exams.  A letter grade will be assigned based on the percentage of total possible points.  A= 90%-100%, B= 80%-89%, C= 65%-79%, D= below 65%, F= below 50%.  Plus and minus grading will be used.
