Semester: Spring 2015Instructor: Clark M. Butler, PE

Office: EB 3.04.30A

Phone (Cell): (210) 275-7486

Office Hours: M/F10:00-11:30 am and by appointmentClass Meetings: MWF 9:00-9:50 am, EB 3.04.30

Grading:

The following are the grade weights and tentative dates for Exams and Assignments. Please check

the Blackboard during the semester for updates.

1. Midterm Exam 1 (Chapters 1-6) 30% February 23, 2015

2. Midterm Exam 2 (Chapters 7-9) 30% April 6, 2015

3. Homework See Homework Policy

4.

Design/Analysis Project 15% April 20, 20155. Final (Comp. with emphasis on Chapters 10, 14) 25% May 5, 2015

Final letter grades will be assigned as follows (scores rounded to nearest whole percentage):

A = 90-95, A+ = 96-100 % B = 80-85 %, B+ = 86-89 % C = 70-75 %, C+ = 76-79 %D = 60-69 % F = 59 % and below

Grade Curving: Grades for an individual exam may be curved at the Instructors discretion when

the class average falls below an acceptable level. Students will be advised when exam gradecurving has been implemented and the formula used to compute the numeric value of the curved

grade.

Grade Disputes:If a student feels an exam, paper, or homework set was graded unfairly, or if there

is an error in the grading, it should be brought to the attention of the Instructor within one week

after the graded material is handed back (except for Final). Scores will notbe reconsidered beyondone week after they are handed back.

Reading Assignments: All reading assignments are listed in the Lecture Schedule and should be

completed in advance of class to optimize the benefit of the lecture. No grade will be assigned for

completion of the reading assignments. However, to do well in this course, it is highlyrecommended that you keep up with the reading assignments. One of the most effective ways to

gain expertise in this subject is to complete your reading assignment before each lecture and thenask questions during the lecture to clarify your understanding as required. You are also encouraged

to read the reference material to enhance your understanding of the concepts.

Part B General Course Information and Policies (continued)

Homework Policy: Beginning with the 1/14/2015 and ending with the 4/24/2015 lectureshomework problems are assigned according to the homework assignment schedule included in the

Lecture Schedule. Solutions should be ready for grading one week following the assignment. All

problem set solutions should be kept in a notebook and brought to each class. Problem sets shall be

randomly selected for grading from the 26 sets assigned during the semester. If you are absentwithout prior notification or for other unexcused reasons on the day a homework set is collected

for grading, you will receive a zero. Homework solutions will be posted on Blackboard followingthe due date. Your homework is a Bonus Credit and will be graded and expressed as a

percentage. At the end of the semester your homework percentage will be divided by 10 and

added to your overall weighted exam average only if your weighted exam average is 70% or

better. If your weighted exam average is below 70%, your homework will not count.

Homework Rules: Perform all work on one side of the "Engineer's Computation Pad" paper. Do not write on

the back of the page. Place your name, the date, the assignment number, and the page

number in the right-hand corner of each page. Use one (1) staple in the upper left-hand corner. Exercise care when treating units. Answers without appropriate units are meaningless.

Be neat. If your work is sloppy, it will not be graded.

Final answers should be clearly identified and given to the number of digits that is consistentwith the most significant problem parameter. That is, for example, if velocity is the desired

solution parameter and the smallest number of digits of given velocity data is three, the

velocity answer should be provided to three digits.

Design/Analysis Project: The course project is designed to demonstrate your ability to developand/or analyze a compressible flow d es i g n problem in more depth than time allows for our

normal homework problems using both the accumulated knowledge obtained in this course andoutside research. You are required to document your project activity in written report

format. In general, teams of 2 or 3 students will work together and select one of the three

topics listed below on or before March 6, 2015. Your instructor will provide the design constraints.

Airplane Internal Bulkhead Pressure Loads During a Sudden Decompression Event Turbine Engine Bleed Air Wing Anti-Icing System Sizing Supersonic Airplane Engine Inlet Preliminary Design

The final report will clearly define in a table the name of each student responsible for the

design/analysis and presentation contained in each section/subsection of the report. Class periodson April 15 and April 17 will be dedicated to brief project presentations by each team. The final

report must be submitted by April 20, 2015.

Final: The Final Exam will be comprehensive with an emphasis on the material covered afterthe second mid-term exam and will be comprised of both computational problems

demonstrating the depth of your knowledge and True/False and Multiple Choice questions

demonstrating the breath of your general gas dynamics knowledge.

Part B General Course Information and Policies (continued)

Classroom Policy:1. Cell phones must be turned off (that means absolutely no text messaging during class).

2. Excessive private conversation with classmates during the lectures is to be avoided.

Make-up exams: Exams can only be made up because of illnesses or other serious emergencies.Emergencies other than medical require notice prior to class for consideration. Medical

emergencies require valid written documentation (e.g. letter from doctor) explaining the situation.

Keep records: Please retain your homework Notebook including graded homework sets and exams at

least until you receive your final grade. You will be asked to produce these if there are any

questions or complications regarding records during the semester.

Attendance policy: Attendance at all class meetings is expected. Failure to attend lectures can only

diminish your performance and potentially result in a zero if you are not present when a homeworkset is collected for grading.

Academic honesty: There is no tolerance for academic misconduct. All homework assignments areexpected to be completed independently. It is acceptable to discuss the homework problems with

each other but it is unacceptable to copy the solutions from each other. See

http://www.utsa.edu/infoguide/appendices/b.html

University Codes: The Student must be acquainted and comply with the university's code, policies,

and procedures involving academic misconduct, grievances, sexual and ethnic harassment, and

discrimination based on physical handicap.

Office Hours: My office is in room 3.04.30A in the Engineering Building and my office hours are

M/F 10:00-11:30 AM. If you need to see me outside these hours, please email me in advance. I alsoencourage you to contact me by email [email protected] questions not requiring a

personal meeting.

Disability: Students with disabilities are encouraged to consult with the UTSA

Disability Services (http://www.utsa.edu/disability/students.htm ) for arrangements to

accommodate special needs.
