Syllabus for EGM-321

THERMODYNAMICS


COURSE DESCRIPTION

Thermodynamics is a study of the science of energy. Thermodynamics deals with equilibrium states and changes from one equilibrium state to another. Words like equilibrium, states, phases, thermodynamic intensive/extrinsic properties, systems, control volumes, processes, and cycles will be defined and used to show all aspects of energy and energy transformations. From the fundamental concept of conservation of energy, comes the First Law of Thermodynamics (attributed to Lord Kelvin and others back around 1850) where energy is shown to be a thermodynamic property. The fundamental concept of conservation of mass is used in conjunction with the conservation of energy to solve thermodynamic problems involving mass flowing across system boundaries along with various energy transport mechanisms (heat, mechanical work, non-mechanical work) that can occur.

The Second Law of Thermodynamics asserts that energy has quality as well as quantity where actual processes occur in the direction of decreasing quality of energy. The second law is used to develop the absolute thermodynamic temperature scale. Its application to cycles and cyclic devices, such as the Carnot heat engines, refrigerators, and heat pumps, will be studied. Expressions for thermal efficiencies and coefficients of performance for reversible heat engines, heat pumps, and refrigerators are included.

The thermodynamic property called entropy is explained by studying its uses in commonly encountered engineering processes. Unlike energy, entropy is a non-conserved property. A special class of idealized processes, called isentropic processes, is examined for entropy changes that take place during processes involving pure substances, incompressible substances, and ideal gases.

The application of thermodynamics to power cycles and refrigeration cycles concludes the material in this course. Of particular interest is the vapor power cycle in which the working fluid is alternately vaporized (steam) and condensed (liquid). Ways to modify the basic Rankine cycle to increase the cycle thermal efficiency will be discussed.

COURSE OBJECTIVES

After completing this course, students will be able to:

  1. Calculate unknown thermodynamic parameters using unit systems (SI and English) and the proper number of significant figures.

  1. Use thermodynamic definitions to express thermodynamic fundamental concepts (such as system state, state postulate, equilibrium, process, cycle).

  1. Explain the First Law of Thermodynamics using the principle of energy conservation. (Consider a fluid flowing across a control surface of a control volume; it carries energy across the control surface in addition to any energy transfer across the control surface that may be in the form of heat and/or work).

  1. Obtain values for thermodynamic properties (such as pressure, temperature, volume, density) of pure substances using instrumentation, ideal-gas equation of state, thermodynamic tables, thermodynamic charts.

  1. Solve energy balance problems for closed (fixed mass) systems that involve heat and work interactions for general pure substances, ideal gases, and incompressible substances.

  1. Apply conservation of mass principle and conservation of energy principle to steady-flow and unsteady-flow processes where energy and mass cross a control surface in control volumes.

  1. Explain the Second Law of Thermodynamic in terms of reversible and irreversible processes involving thermal energy reservoirs, heat engines, refrigerators, heat pumps.

  1. Determine the expressions for the thermal efficiencies and coefficients of performance for reversible heat engines, heat pumps, and refrigerators.

  1. Calculate the entropy changes that take place during processes for pure substances, incompressible substances, and ideal gases.

  1. Apply thermodynamic principles to power producing devices that operate either in closed cycle or open cycle modes.

  1. Read carefully the entire Syllabus, making sure that all aspects of the course are clear to you and that you have all the materials required for the course.

  1. Take the time to read the entire Online Student Handbook. The Handbook answers many questions about how to proceed through the course, how to schedule exams, and how to get the most from your educational experience at Thomas Edison State College.

  1. Arrange to take your examination(s) by following the instructions in this Syllabus and the Online Student Handbook.

  1. Familiarize yourself with the learning management systems environment—how to navigate it and what the various course areas contain. If you know what to expect as you navigate the course, you can better pace yourself and complete the work on time.

  1. If you are not familiar with Web-based learning be sure to review the processes for posting responses online and submitting assignments before class begins.

Study Tips

Consider the following study tips for success:

  1. To stay on track throughout the course, begin each week by consulting the course Calendar. The Calendar provides an overview of the course and indicates due dates for submitting assignments, posting discussions, and scheduling and taking examinations.

  1. Check Announcements regularly for new course information.

ACADEMIC INTEGRITY

Students at Thomas Edison State College are expected to exhibit the highest level of academic citizenship. In particular, students are expected to read and follow all policies, procedures, and program information guidelines contained in publications; pursue their learning goals with honesty and integrity; demonstrate that they are progressing satisfactorily and in a timely fashion by meeting course deadlines and following outlined procedures; observe a code of mutual respect in dealing with mentors, staff, and other students; behave in a manner consistent with the standards and codes of the profession in which they are practicing; keep official records updated regarding changes in name, address, telephone number, or e-mail address; and meet financial obligations in a timely manner. Students not practicing good academic citizenship may be subject to disciplinary action including suspension, dismissal, or financial holds on records.

Academic Dishonesty

Thomas Edison State College expects all of its students to approach their education with academic integrity—the pursuit of scholarly activity free from fraud and deception. All mentors and administrative staff members at the College insist on strict standards of academic honesty in all courses. Academic dishonesty undermines this objective. Academic dishonesty takes the following forms:

  1. Cheating
  2. Plagiarizing (including copying and pasting from the Internet without using quotation marks and without acknowledging sources)
  3. Fabricating information or citations
  4. Facilitating acts of dishonesty by others
  5. Unauthorized access to examinations or the use of unauthorized materials during exam administration
  6. Submitting the work of another person or work previously used without informing the mentor
  7. Tampering with the academic work of other students

Academic dishonesty will result in disciplinary action and possible dismissal from the College. Students who submit papers that are found to be plagiarized will receive an F on the plagiarized assignment, may receive a grade of F for the course, and may face dismissal from the College.

A student who is charged with academic dishonesty will be given oral or written notice of the charge. If a mentor or College official believes the infraction is serious enough to warrant referral of the case to the academic dean, or if the mentor awards a final grade of F in the course because of the infraction, the student and the mentor will be afforded formal due process.

If a student is found cheating or using unauthorized materials on an examination, he or she will automatically receive a grade of F on that examination. Students who believe they have been falsely accused of academic dishonesty should seek redress through informal discussions with the mentor, through the office of the dean, or through an executive officer of Thomas Edison State College.

Plagiarism

Using someone else's work as your own is plagiarism. Although it may seem like simple dishonesty, plagiarism is against the law. Thomas Edison State College takes a strong stance against plagiarism, and students found to be plagiarizing will be severely penalized. If you copy phrases, sentences, paragraphs, or whole documents word-for-word—or if you paraphrase by changing a word here and there—without identifying the author, then you are plagiarizing. Please keep in mind that this type of identification applies to Internet sources as well as to print-based sources. Copying and pasting from the Internet, without using quotation marks and without acknowledging sources, constitutes plagiarism.  (For information about how to cite Internet sources, see Online Student Handbook > Academic Standards > "Citing Sources.")

Accidentally copying the words and ideas of another writer does not excuse the charge of plagiarism. It is easy to jot down notes and ideas from many sources and then write your own paper without knowing which words are your own and which are someone else's. It is more difficult to keep track of each and every source. However, the conscientious writer who wishes to avoid plagiarizing never fails to keep careful track of sources.

Always be aware that if you write without acknowledging the sources of your ideas, you run the risk of being charged with plagiarism.

Clearly, plagiarism, no matter the degree of intent to deceive, defeats the purpose of education. If you plagiarize deliberately, you are not educating yourself, and you are wasting your time on courses meant to improve your skills. If you plagiarize through carelessness, you are deceiving yourself.
