Units
The course will be taught using both SI and
English units.
Grading:
Homework 10%
Best 3 of 5 quizzes 10%
Design Problem 10%
1st Exam 20%
2nd
Exam and Final 25%
Grades
will be converted to a T score by the following formula,
T-score = (Exam Score - Class Mean)/
Class Standard Deviation
|
T-Score |
Grade |
|
1.2 or higher |
A |
|
1.0 to 1.199 |
A- |
|
.8 to.999 |
B+ |
|
0.4 to .799 |
B |
|
0.2 to .399 |
B- |
|
0.0 to .199 |
C+ |
|
-.4 to -.001 |
C |
|
-.6 to -.399 |
C- |
|
-.8 to -.599 |
D+ |
|
-1.0 to -.799 |
D |
|
-1.0 or less |
F |
The T
score will set the minimum grade that can be given. The T score grade can be improved with better
grades in the latter part of the course demonstrating a competence in subjects
with a poor grade in the first part of the course.
There
will be 5 quizzes, two exams and a final.
The 5 quizzes will be unannounced. The lowest 2 quiz grades will be
excluded.
A
design problem will be assigned. The
design problem will be graded according to the results achieved. Example:
With cycle efficiency as a design problem objective the highest
efficiency will be A with lower grades for lower efficiencies..
All
exams are open book, closed notes and closed homework.
Course
notes for the coming week will be posted on the course web site on Friday
Homework
is due on Monday in class or my office before
Integrity Policy:
There is nothing more dishonorable for an
engineer, short of his work causing loss of life or property, than to present
the work of another as his own. This can
happen in patent applications, reports, presentations, and technical
papers. Dishonesty in course work is the
start of this slippery slope that ends in news stories such as we have seen
reported last year or worse. Pressure
may be felt in school however it is more difficult, not easier, to maintain
integrity in practice.
Presenting course work of another as your
own will result in a reduction in grade usually to an F.
Course Outline:
The course will begin with a brief review of
thermodynamics fundamentals, Chapters 1 thru 7. The course will be a detailed
consideration of a variety of energy systems with thermodynamics fundamentals
that apply to each section reviewed again.
