Course Objectives Upon completion of this course, a student should be able to: 1. Understand the fundamental basis of the first and second laws of thermodynamics. 2. Estimate thermodynamic properties of pure gases and liquids using equations of state. 3. Develop mass and energy balance equations necessary to solve reactive and non-reactive steady-state and transient systems by hand or by computer using process simulation software. 4. Use tables, charts, or software to estimate physical property data needed to solve material and energy balances. 5. Apply the pertinent mathematical concepts to develop general thermodynamic equations of change. 6. Estimate thermodynamic properties of fluid mixtures. 7. Work ethically with other students, both engaging in discussions and working independently.

Grading Criteria The grade will be determined according to the following weighting criteria: Midterm 1: 25 % Midterm 2: 25 % Final exam: 30 % Quizzes: 10% Homework: 10 % In borderline cases, class participation will be factored into the course grade. Class Attendance Students are strongly encouraged to attend all lectures, although attendance is not required. It is student’s responsibility to obtain the information (e.g. notes, assignments, and announcements) that they have missed due to their absence. Format for Exams, Quizzes, and Homeworks  Write name, date, ECH 3101, and exam/quiz/homework number on top of the front page.  Write page number on each page.  Write (neatly) on only one side of 8.5x11 inch sheets of paper. Staple all pages together.  Begin each new problem on a new page. Clearly indicate the problem number.  Clearly identify solutions by boxing all final and intermediate answers.  Include enough details to justify your solutions. Exam and Quiz Policy  The final exam is scheduled to take place on Thursday, May 3, 3:00 pm - 5:00 pm (group 3D).  Dates of the midterm exams will be announced in class and posted on the course website.  Exams and quizzes will be rescheduled only for those students who missed them due to an acceptable reason (illness, serious family emergencies, military obligation, religious holidays, and participation in official university activities) as listed in the undergraduate catalog (http://www.registrar.ufl.edu/catalog/). It is required that whenever possible the student notifies the instructor about the situation before the exam.  Students arriving late for a quiz/exam will be given only the balance of time remaining to complete their work unless an acceptable reason (see above) is provided.  Students may not leave the room during a quiz/exam except in emergencies.  Students may use their course notes and the textbook during quizzes but not during the exams. Use of any other material is not allowed.  It is recommended that students bring a scientific calculator to all exams. However, the use of cell phones, laptops, tablets, and similar electronic devices is not allowed.  Only one solution per problem should be turned in. If a student turns in two or more different solutions for the same problem, all of them will be graded but only the lowest of these grades will

be counted towards the exam or quiz grade. The motivation for this policy is that the students should learn to identify correct solutions without outside help.

    

Homework Policy A failing grade will be assigned to students whose cumulative homework grade is less than 50%. Homework will be assigned on a 1-2 week basis. Solutions of homework assignments must be turned in at the beginning of class on the due date. Late homework submissions will not be accepted. Homework solutions will be posted on the e-learning website after the due date. Academic Honesty

All students admitted to the University of Florida have signed a statement of academic honesty committing themselves to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a student at the University of Florida and to be honest in all work submitted and exams taken in this class and all others. Work submitted must be produced individually by each student, except for tasks explicitly assigned to a group by the instructor. All work submitted individually in the form of exams, homework, computer projects, etc., is subject to the following pledge: On my honor, I have neither given nor received unauthorized aid in doing this assignment. Cooperation Policy  Students are free to consult among themselves on the approach taken to solve any homework problem. However, copying homework solutions is a violation of the Honor Code. In particular, showing other students a copy of the actual manuscript or computer code to be submitted as homework is not allowed. Acceptable consultation includes discussing which equations should be used for solving a problem, writing down relevant relationships, etc.  No consultation among students is allowed during quizzes and exams. Plagiarism Students are not permitted to represent as their own work all or any portion of the work of another. Plagiarism includes (but is not limited to) submitting a document or assignment which in whole or in part is identical or substantially identical to a document or assignment not authored by the student. Sanctions Since ethical behavior in science and engineering is equal in importance to specific knowledge, the instructor will assign a non-passing letter grade to students who violate academic honesty standards, regardless of the violator's grade performance in class.
