EAS 4101 - Aerodynamics – Spring 2011
1/3
4/21/11, Final Exam review
Announcements:
1.
The final exam information:
Exam Group 28A, Thur., 4/28/11, 7:30 – 9:30 am in FLG 220.
2.
The exam will cover up to and including boundary layers (not separation) and through HW#8.
3.
The exam will cover up all material presented in the class.
It will be comprehensive in nature,
but will somewhat emphasize material covered after exam 2.
Exam Format:
1.
Bring a pencil, eraser, etc.
DO NOT bring your notes, textbook, calculator, crib sheet, etc.
2.
I anticipate that we will have several problems and several short-answer questions with the
points per problem/question clearly labeled.
Please see prior exams for examples.
3.
Below are topics that you are responsible for, the majority has been covered in class, but some
material just covered via reading assignments will also be included on the exam.
Exam Topics:
1.
