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 1:00 PM.  Homework solutions will be posted on the course web site the day after they are due.

 

 

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 6. The course will be a detailed consideration of a variety of energy systems with thermodynamics fundamentals that apply to each section reviewed again.
