Introduction
to Fluid Mechanics - 4 CREDITS
http://www.egr.msu.edu/~lishug/courses/321
Course Objective
This
course is designed to provide Civil and Environmental Engineering students with
basic understanding of the fundamental principles of fluid mechanics and
acquire experience in some applications to engineering practice. At the end of
the semester, a student is expected to know
![*]()
how to determine
pressure in a static liquid; write manometer equations; calculate the magnitude
and location of point forces due to fluid pressure on a plane surface.
![*]()
how to use the Bernoulli Equation to determine how changes in fluid
velocity influence fluid pressure.
![*]()
how to use conservation of mass, energy and momentum with a
control volume to analyze or design a flow system.
![*]()
how to use dimensional analysis to present experimental data;
![*]()
how to analyze the flow in simple pipe systems that
incorporate friction losses, minor losses and in some cases a pump.
![*]()
how to write technical lab reports and memos based on
quantitative data obtained to answer a question.
Instructor and Office
Hours:
Dr.
Shu-Guang Li (http://www.egr.msu.edu/~lishug/
), Associate Professor of Civil and Environmental Engineering, A133 Research
Complex – Engineering, emails ( lishug@egr.msu.edu), and
telephone (432-1929). Dr.
Li and the TA's are available during their scheduled office hours to help when
you get stuck. Their office hours are
Mondays/Dr. Li 10-10:30AM, EB3550
Tuesdays/Nicole 4-5PM (EB 3568); David Adam 3-5PM EB3580
Wednesdays/Dr. Li 10-11AM, EB3550; Andreanne 2-3PM (EB3568),
David Adam 2-5PM, EB3580
Thursdays/Nicole 12:30-1:30PM (EB3568)
Fridays/Dr. Li
10–11AM, EB3550
You will make the best use of their time and your own by
having identified specific questions that you need to have answered before
talking to them. Often by
identifying the issues you need help with, you will be able to find the answer
yourself.

A Brief
Introduction to Fluid Mechanics, Second Edition, D.F. Young, B.R. Munson and
T.H. Okiishi, Wiley
Reading and studying
the assigned material in the text is essential to developing sufficient
understanding of fluid mechanics to do well in the course. The solved problems
and figures are often helpful and should be studied. The video segments contained in the fluid mechanics
phenomena CD (attached with your text) is very interesting and you should try
to take advantage of it in visualizing fluid flow.

Final Exam (same classroom)
|
Comprehensive,
Closed book, closed notes with two review sheets |
|
|
About 1/3 of lecture time will be
devoted to a brief summarization of the most important aspects of our
understanding of fluid mechanics.
The other 2/3 will be devoted to in-class solution of problems and provides
an opportunity for you to have questions answered. An extensive set of notes dealing with the material covered
is included in your course pack.
Lectures will focus only on the more difficult aspects; you are expected
to develop your understanding of other material outside of class.
The lab assignments provide an
opportunity for you to work with a physical system (one you can touch and
observe) as opposed to a purely conceptual system (one you can only imagine).
Working with a physical system will help you develop your appreciation of the
nature of a fluid and its behavior. The lab assignments also provide an ideal
opportunity for you to practice technical writing. As an engineer you will need
to be able to communicate your understanding to others. Effective technical
writing skills provide a way to accomplish this. Study has shown that development of effective writing
skills requires continued effort over a long period of time. Consequently, this course and several
others in your junior and senior years were selected by the CEE Faculty to
provide this training and a technical writing consultant has been hired to
assist in this effort.
Prerequisites:
MTH
235 or concurrently and completion of Tier I writing requirement. Statics. Open
only to juniors or seniors in the Department of Civil and Environmental
Engineering or in the Biosystems Engineering major. Not open to students with
credit in ME 332
Homework:
Homework will be
assigned to give you practice with problems and to encourage you to read and
study the text in advance of our discussions in lecture. Problems will be posted on the class
website. They are selected from those in the text that have answers provided so
that you have a basis for checking yourself.
Study Groups:
Study groups, if used
correctly, are an aid. Use the
group to help you understand concepts required to solve problems
as opposed to simply providing a pattern or recipe for obtaining a solution to
a particular problem type. Study groups are used correctly when individuals are
expected to explain and defend the approach they have suggested to solving or
approaching a problem.
Quizzes:
The seven quizzes will
test your understanding of fluid mechanics. There will be an emphasis on the numerical solution of word
problems like the ones done in class and assigned for homework. There will also
be questions to test the understanding you have developed of basic concepts and
principles through your study outside of class.
Final
Exam:
The final exam will be comprehensive
and cover the entire course. It will be closed-book and closed notes, you can
bring two 8 by11 review sheets.
Grading
Scale:
4.0: 92-100 1.5: 65-69
3.5: 86-91 1.0: 55-64
3.0: 80-85
2.5: 75-79 0.0: 00-54
2.0: 70-74
Course
Grade:
Weighted score will be computed and
the grade determined on the basis of the grading scale indicated. I retain the option to curve the final
scores but you should assume that I will not do that.
