Grade ranges are determined according to University Bulletin criteria applied to each area. The grade ranges for each exam will be announced when exams are returned. The "traditional" factors (i.e.90-100,80-89,70-79,60-69,0-59) will  not be observed.

The following summarizes the criteria published in the University Bulletin: A: Superior, B: Good, C: Acceptable, D: Passing, F: Failing

Benchmarks for Grades

A - Student clearly demonstrates an in-depth technical understanding of the concepts. Able to offer different technical viewpoints and solutions to a problem. Demonstrates the ability to apply the concepts creatively. Consistently carries problems to a final and justified solution. Demonstrates technical leadership in the subject.

B - Student demonstrates a technical understanding sufficient for solving the majority of problems. Able to propose at least one technical solution or viewpoint to a problem. Consistently carries problems to a satisfactory solution. Can explain and justify a conclusion or approach most of the time.

C - Student demonstrates a technical understanding sufficient for solving straightforward problems but may have trouble with more complex variations or situations. Carries problems through to an adequate solution most of the time. Able to explain and justify conclusions or approaches for many cases but with uncertainty.

D - Student's ability to apply the concepts even to straight-forward problems is marginal. Carries problems through to an adequate solution only sporadically. The ability to explain or justify conclusions is weak and sporadic. There would be a question with regard to the ability to work in the area in a professional chemical engineering setting.

F - Student's ability to apply the concepts to problems is seriously in question. The ability to do professional chemical engineering work in the area undemonstrated.

 

Course Outcomes:

 

Upon successful completion of this class, students should be able to:

 

  1. Explain if the units in an equation are consistent and convert data between different systems of units with an appropriate number of significant figures.
  2. Employ linear interpolation to calculate intermediate values between given points in a table or graph.  Find the most appropriate equation of a line through a set of data where the variables are related in a logarithmic, semi-logarithmic, or linear manner.
  3. Explain the concepts of mass, density, specific gravity, chemical composition, concentration, pressure and temperature as used to characterize process operations.
  4. Construct and label a flow chart from a written description of a chemical process and calculate the flow rate of process streams from mass, molar and volumetric units given appropriate data.
  5. Explain the fundamental concepts underlying general mass and energy balance equations.
  6. Analyze, develop and solve mass balances for processes involving single and multiple process units for process operations without chemical reaction.
  7. Explain the concepts of recycle, purge, bypass, closed (batch) and open (flow) systems, accumulation, steady state and transient operations, and basis of calculations.  Apply these concepts when developing and solving mass balances.
  8. Explain the concepts of limiting reactant, excess reactants, conversion, stoichiometric ratio, extent of reaction, atomic species balances, yield, and selectivity.  Employ these concepts when developing and solving mass balances involving reactive systems.
  9. Employ the ideal gas law to calculate thermodynamic properties (P, V, n, and T) of pure gases and gas mixtures applying the concepts of partial pressure, gauge and absolute pressure, relative and absolute temperature.  Distinguish between partial pressure and vapor pressure.

Class Announcements and Class Schedule

Class announcements such as assignment clarifications, etc. will be made verbally in class, or through the course class page under Chambers. It is your responsibility to attend class, and check the course page regularly. Please refer to the Class Schedule regularly for a daily schedule of reading assignments, homework assignments, and test dates, as well as other class announcements.

 

Tests:

Please see the class schedule for Test and Final Exam dates.

  • Makeup exams will not be given without a valid university excuse. Unexcused absences receive a zero.
  • Students arriving after the start time of any examination will not be given additional time to complete the examination.
  • Assigned seating may be used for exams.
  • Use of Electronic Devices (except for Department-approved calculators) is prohibited during any examination. No cell phones, Blackberry’s, PDA’s, laptops’s, iPOD’s, iPHONE’s, etc.

 

Assignments, Quizzes, Project and Attendance:

 

Homework:

·         Homework is due at the beginning of class as indicated on the Class Schedule.

·         Late homework (without an official university/medical excuse) will not be accepted.

·         You may work together with classmates on homework but the work you turn in is to represent your personal effort and written in your style. Working in study groups is encouraged.

·         The format of the homework is to be consistent with published departmental format and style sheets. Credit will be lost for unclear or incomplete work. Graded homework will be returned in the part of the class it is assigned (either lecture or lab).

 

You must obtain a minimum of 50% on homework assignments and also a minimum of 50% of the quizzes in order to make a C or better in this class, regardless of your grades on the hour exams or the final exam. (i.e. this requirement stands alone). If you do not turn in homework you will not pass this course and you will receive an F.


The Class Schedule should be consulted for homework assignment due dates. Special notes will also be posted.

 

Quizzes:

·         Unannounced "pop" quizzes may be given to reinforce important principles and to encourage preparation for class.

·         Quizzes will not be able to be made up without an official university/medical excuse.

·         Quizzes will generally be given at the beginning of class. If you arrive late, do not expect to receive additional time.

 

Project: An in depth group project will be assigned and will be due the last week of class. This project will involve application of several topics covered throughout the course. It will also involve the preparation of a written document and an oral presentation. Project lab attendance and project assignments will also be included in the project grade.

 

Attendance: Class and lab attendance is required. Both project and homework grades will include attendance components. Tests, quizzes, and final will not be made-up without an official medical/university excuse.

 

Other Important Notes and Information:

 

1. On problems you are expected to present solutions which an engineer can logically follow to ascertain how the answer was obtained. If you only put the answer without showing how the answer was obtained in a clear logical method, you may receive reduced or no credit for the answer (even though it may be the correct final answer). Also if the answer is correct, but the method is incorrect, credit will be reduced. For homework, but not for tests, you will receive credit for effort, so it is worthwhile to turn in an attempt to work the problem even if you are unsure if your approach is correct.

 

2. Check your email (campus) and your internet course page between each class meeting for possible important information regarding CHEN 2100 Class. The instructor will send all class emails to your Auburn University e-mail address. You may wish to have your Auburn e-mail automatically forwarded to another address. See IT web page or call 844-4944 to set up e-mail forwarding

 

3.Homework solutions will be presented after the homework is due.  Any adjustments to homework grades should be handled within two class periods after the assignment solutions are presented (submit a request to Professor Chambers via e-mail and e-mail/meet with the Grader, who will then correspond with me). If you believe a grading mistake is made in an examination, you must return your examination papers with a written description of the mistake to Professor Chambers within two class periods following the presentation of examination solutions. No requests for regrades will be accepted after this two class period. When a regrade is requested, your entire examination may be regraded.

 

4. Appropriate collaboration for solution of homework is allowed and study groups are encouraged. However, outright copying by a student from another student’s paper will be considered cheating. Ethical and professional behavior is expected at all times. You are to submit only your own work on examinations, homework assignments, and research papers. Any evidence of cheating or any other form of dishonesty will result in appropriate action as specified in the Tiger Cub (see below).

 

Special Accommodations:

Students needing special accommodations (for school events, personal circumstances, disabilities, etc.) should bring that need to my attention as soon as possible, along with the appropriate written verification.

 

Request for accommodation for disabilities is taken very seriously and should be provided the first week of class, so we can meet student needs promptly. To set up a meeting, please contact me by email. Bring a copy of the Accommodation Memo and an Instructor Verification Form to the meeting. If you do not have an Accommodation Memo but need accommodations, make an appointment with the Auburn Program for Disabilities, 1244 Haley Center, 844-2096, Dr. Kelly Haynes, Director and refer to their website under the AU Academic section.

 

 Appropriate University events and personal circumstances: email me at least 24 hours in advance of the class you will miss and give your reason for missing. If you are sick, in addition you will need to give the instructor a University medical excuse from the Medical Clinic. Class attendance is required, the only excused absences are excused illness and excused professional travel.

 

Electronic Devices:

Electronic devices such as cell phones, pagers, and alarms must be turned off or set to silent mode throughout class. Disruptions of the class during examinations may result in loss of 10% of the exam credit.

 

Academic Honesty: In order to articulate fully its commitment to academic honesty and to protect members of its community from the results of dishonest conduct Auburn University has adopted policies to deal with cases of academic dishonesty. These policies are intended not only to emphasize the imperative of integrity, but also to protect the rights of all members of the university community. The complete academic regulations concerning cheating are located in the Tiger Cub. The following information is the implementation and delineation of those policies by the above faculty member.

  • When a student is suspected of violating academic honesty standards, the faculty member will, as soon as reasonably possible, notify the student of the suspected infraction, seek the student's explanation, undertake any further investigation the faculty member considers appropriate, and initially determine whether a violation of the academic honesty policy has occurred.
  • If an act of academic dishonesty is determined to have occurred, for a first offense, one of the following sanctions will be imposed, depending on the gravity of the offense: an "F" for the assignment or exam, reduction of the course grade, or failure for the entire course, or other action deemed appropriate by the faculty member. Examples of the latter actions include, but are not limited to, requiring the student to re-take the exam, re-complete an assignment, or complete an assigned exercise.
  • Subsequent acts of academic dishonesty will be referred to the Academic Honesty Committee for action. This action will result in an official disciplinary record for the student(s). Any student who believes that he or she has been accused of academic dishonesty unjustly may request a meeting with the faculty member and/or department chair. Likewise, if the punishment is viewed by the student as excessive, given the circumstances, a review process may be initiated. If such a meeting does not resolve the disagreement, and the student still believes the charge to have been unjust, he or she can appeal to the Academic Honesty Committee.

Forms of Academic Dishonesty:

Plagiarism is the inclusion of someone else's words, ideas, or data as one's own work. When a student submits work for credit that includes the words, ideas, or data of others, the source of that information must be acknowledged through complete, accurate, and specific references, and, if verbatim statements are included, through quotation marks as well. By placing his/her name on work submitted for credit, the student certifies the originality of all work not otherwise identified by appropriate acknowledgments. Plagiarism covers unpublished as well as published sources. Examples of plagiarism include, but are not limited to: 1. Quoting another person's actual words, complete sentences or paragraphs, or an entire piece of written work without acknowledgment of the source; 2. Using another person's ideas, opinions, or theory, even if it is completely paraphrased in one's own words without acknowledgment of the source; 3. Borrowing facts, statistics, or other illustrative materials that are not clearly common knowledge without acknowledgment of the source; 4. Copying another student's essay test answers; 5. Copying, or allowing another student to copy, a computer file that contains another student's assignment, and submitting it, in part or in its entirety, as one's own; or 6. Working together on an assignment, sharing the computer files and programs involved, and then submitting individual copies of the assignment as one's own individual work. Students are urged to consult with individual faculty members, academic departments, or recognized handbooks in their field if in doubt regarding issues of plagiarism. Fabrication is the use of invented information or the falsification of research or other findings. Examples include, but are not limited to: 1. Citation of information not taken from the source indicated. This may include the incorrect documentation of secondary source materials; 2. Listing sources in a bibliography not used in the academic exercise; 3. Submission in a paper, thesis, lab report, or other academic exercise of falsified, invented, or fictitious data or evidence, or deliberate and knowing concealment or distortion of the true nature, origin, or function of such data or evidence; or 4. Submitting as your own any academic exercises (e.g., written work, printing, sculpture, etc.) prepared totally or in part by another. Cheating is an act or an attempted act of deception by which a student seeks to misrepresent that he or she has mastered information on an academic exercise that he or she has not mastered. Examples include, but are not limited to: 1. Copying from another student's test paper; 2. Allowing another student to copy from a test paper; 3. Unauthorized use of course textbook or other materials such as a notebook or electronic data files to complete a test or other assignment from the faculty member; 4. Collaborating on a test, quiz, or other project with any other person(s) without authorization. 5. Using or processing specifically prepared materials during a test (e.g., notes, formula lists, notes written on the students clothing, etc.) that are not authorized; or 6. Taking a test for someone else or permitting someone else to take a test for you. Academic Misconduct includes other academically dishonest acts such as tampering with grades or taking part in obtaining or distributing any part of an administered or unadministered test. Examples include, but are not limited to: 1. Stealing, buying, or otherwise obtaining all or part of an administered or unadministered test; 2. Selling or giving away all or part of an administered or unadministered test including questions and/or answers; 3. Bribing any other person to obtain an administered or unadministered test or any information about the test; 4. Entering a building or office for the purpose of changing a grade in a grade book, on a test, or on other work for which a grade is given; 5. Changing, altering, or being an accessory to the changing and/or altering of a grade in a grade book, on a test, a "change of grade" form, or other official academic records of the University that relate to grades; 6. Entering a building or office for the purpose of obtaining an administered or unadministered test; 7. Continuing to work on an examination or project after the specified allotted time has elapsed; 8. Any buying or otherwise acquiring any theme report, term paper, essay, computer software, other written work, and handing it in as your own to fulfill academic requirement; or 9. Any selling, giving, or otherwise supplying to another student for use in fulfilling academic requirements any theme, report, term paper, essay, computer software, other written work.
