Course Description:

Principles of fluid dynamics as applied to biological systems; Newtonian and non-Newtonian fluid flow processes; theory and application of pumps and low-pressure fans; flow measuring devices and techniques.  3 hours credit.

Course Outcomes:

At the conclusion of the course, the student should be able to:

1.      Demonstrate high proficiency in the areas of fluid statics, fluid heat and energy considerations, and conservation of mass, momentum and energy through practical problem solving.

2.      Perform independent, complete analysis of pipe system operating characteristics for compressible and incompressible fluids.

3.      Identify variables involved in fluid flow processes and apply similitude principles to develop experimental scaling parameters.

4.      Collect and analyze data necessary for assessing pump performance.

5.      Analyze and design non-erodible open channels.

Prerequisite:

ME 330, Fluid Mechanics, or CE 341, Fluid Mechanics I.

Attendance

Attendance is not mandatory.  In my experience, however, there is a high correlation between attendance and ability to master the subject material or, perhaps more importantly, between attendance and final grade.  You have paid for the course, so I encourage you to get the most out of your money.  Besides, I will be giving quizzes that will account for 10% of your grade.

I will work with you to make arrangements for making up tests and homework missed as a result of an excused absence (sickness, death in the family, UK-related trips, etc.).  You are responsible for notifying me as far as possible in advance of the absence, or as soon as possible following the absence (e.g., sickness).  Tests and homework will generally not be made up in the case of unexcused absences.

Homework

Except for cases of excused absence, homework is due at the beginning of the class period listed as the due date. No credit will be given for late homework.

Use engineering paper for homework with header information appropriately supplied.  The header information includes (beginning in the left-most block, and proceeding to the right) the course (AEN 343), due date, assignment (e.g., Chap. 3 Homework), your name, and the page number/total pages (e.g., 2/10).  I expect homework to be performed in standard engineering format (i.e., Given, Required, Solution; intermediate results with single underline, final result with double underline or box).  Use a pencil and print legibly.  You may use a computer if and when appropriate or advantageous, but you are responsible for adequately documenting your work.

I encourage you to work together in solving homework problems.  The work you turn in, however, must be a reflection of your own efforts rather than a substantial copy of another person's work.

Communications

I will use e-mail to make any announcements of a short-notice nature.    Let me know if there is a change to the e-mail address you furnish me on the first day of class.

I hope you will feel free to visit with me regarding homework during my posted office hours or at any other time I am available.  As an alternative, you may e-mail me with questions, in which case I will send a reply via e-mail to the entire class.  I recommend that you have access to Microsoft Word or other word processing software capable of converting Word text and displaying Word graphics (most notably, equations).  Make your questions as specific as possible in order to help me answer.
