MAE 210 Thermodynamics - Summer 2005  

 

Catalog Description:

MAE 210 - Thermodynamics (3 cr.). Prerequisite: APMA 110

Includes the formulation of the first and second laws of thermodynamics; energy conservation; concepts of equilibrium, temperature, energy, and entropy; equations of state; processes involving energy transfer as work and heat; reversibility and irreversibility; closed and open systems; cyclic processes. Cross-listed as ChE 202.


Objectives:

a. To gain a firm understanding of the basic concepts, principles and terminology of classical macroscopic thermodynamics, with emphasis on the first and second laws.

b. To develop an understanding of thermodynamic properties of matter and a facility for using sources of property data (tables, graphs, algebraic equations of state, computerized tables).

c. To gain experience in applying first-law principles and property data to the analysis of the operation of energy conversion systems such as heat exchangers, pumps, compressors, engines, and to gain an appreciation for the significance of measures of efficiency.

d. To develop a working appreciation of the second-law concepts of equilibrium, reversibility, entropy generation, and entropy transfer.

e. To apply accumulated skills to the analysis of the operation of energy conversion devices which operate in a cyclic manner, such as vapor-cycle and gas-cycle power systems and refrigeration (heat pump) systems, and to gain some appreciation for the factors which influence the design of such systems.

6. Entropy: Clasius inequality, definition of entropy change, entropy for a closed system, entropy for a control volume, isentropic processes, efficiencies of turbines, pumps, nozzles and compressors.

7. Gas and Vapor Power Systems: Carnot and Brayton air-standard cycles, cycle efficiency, isentropic efficiency, Rankine vapor power cycle.

8. Gas Mixtures: Gas-vapor mixtures, wet and dry bulb temperatures.


Homework:

Homework will be assigned on a regular basis and is due at the beginning of the class period. Homework is to be prepared on 8.5" by 11" paper submitted unfolded. Problems solutions should make use of system diagrams and appropriate graphs whenever possible. Data obtained from tables, charts, or other references (e.g., the CATT2 software on the classroom computers) should be noted as to the source, e.g., "Table ____, pg. ___". Late homework will not be accepted except in the event of illness or excused absence.

 

Homework is unpledged and will be graded on the basis of whether the problems were seriously attempted. While some collaboration and discussion may be useful and educational, particularly when it comes to fundamental principles, students are urged to implement their solutions independently rather than in cooperation with others. You are welcome to call, visit or e-mail me for help during the day. In the spirit of "professional ethics," help received from others should be acknowledged in writing. Simply copying another person's analysis on any problem is unethical and unacceptable.

Please note that thermodynamics is a challenging subject requiring consistent and in depth study. Consequently, you must attend every class and make a good effort to do the homework. There will be an occasional unannounced quiz to encourage you to do so.


Attendance and Classroom Decorum:

Students are expected to attend all classes, and attendance will be taken. A point will be deducted from the final grade of any student for each unexcused absence in excess of one. In extreme cases of habitual absence or tardiness, the student will be dropped from the course.  Remember that missing one class in the short summer session is as if you missed nearly a week of class during the academic year. 

 

The room in which we meet (MEC 216) has a computer for each student and we will use them periodically throughout the course. During class these computers are to be used only for course purposes - and then only when you are instructed to do so. This especially means no e-mailing, netsurfing, working on other courses, etc. The penalty for inappropriate use of the computers is the same as for habitual tardiness or absence.  (You may use them for checking e-mail, etc., if you arrive early for class.)  Please turn off cell phones.   


Quizzes:

The dates for scheduled quizzes and the final are given below.  Generally we will spend at least part of every Friday class on a quiz.  These quizzes will consist of 2-3 problems.  You should bring the textbook with you to class every day since we will often work problems out of there, including some nominally assigned as homework.

 


Grading:

The final grade will be computed on the basis of the following distribution of emphasis:

Homework 15%, Quizzes 55%, Final Exam 25%, Attendance 5%
