Text:    A Brief Introduction to Fluid Mechanics, 3rd Edition, by Munson, Young, Okiishi
Office Hours:    Mondays, 3:30 – 5:00 pm; any time my door is open; or by appointment

## Course Description:

This is an introduction to the basic phenomena and principles of fluid flow. We discuss fluid properties, fluid statics, conservation of mass, momentum and energy. Emphasis is on quantitative analysis of velocities, pressures, shear stresses, and flow forces. The application of basic fluid mechanics concepts to the analysis of pipe flow, and flow over or around objects is stressed in homework assignments and exams. Flow phenomena are illustrated in CD-ROM tutorials and laboratory demonstrations. Measurement of fluid properties, pressures, velocities, and flow forces are performed in laboratory sessions. The course audience is primarily 2nd and 3rd year engineering students with a knowledge of statics, deformable body mechanics and calculus. The course is a prerequisite for courses such as water resources engineering, water and wastewater treatment, geotechnical engineering, heat and mass transfer, and chemical process courses.

## Course Objectives:

Upon completion of this course, students will be able to:
• Determine pressures and forces on submerged bodies
• Analayze flow rates, velocities, energy losses, and momentum fluxes for fluid systems
• Measure and describe fluid flow phenomena
• Analyze, design, and evaluate pumping systems and pipeline components
• Communicate effectively with written reports and engineering graphics

## Course Outline:

PART I: Building a Fluid Mechanics Vocabulary
• Fluid Properties
• Fluid Statics
• Pressure Measurement
• Fluid Forces

PART II: Fluids in Motion

• Conservation of Mass: Continuity Equation
• Conservation of Energy, Part I:  Bernoulli’s Equation
• Conservation of Momentum:  Momentum Equation

Homework (10%):  Puzzle and problem-solving skills are the hallmark of a successful engineer.  You will be expected to complete homework puzzles before the next class period.  You may work on the home problems with your colleagues, but the work you turn in must be your own.  You will be expected to follow the specific Homework Format guidelines for all work done for this course, as shown hereHomework not submitted in the required format will be returned with no grade.  Homework is due at the beginning of the class period.  Solutions to home puzzles and problems will be posted outside my office after the assignment is due.

Late homework will not be accepted without prior arrangement with the instructor.

Quizzes (10%):  You are expected to have completed home puzzle assignments and read the assigned material before the start of class.  Short quizzes may be given at the beginning of any class period to ensure you are ready to learn!

Self-Study Quizzes (no grade):  You are strongly encouraged to make use of web-based self-study quizzes before each class period.  These will be announced in class, and links posted from the course web page.

Laboratory Exercises (20%):  Fluid mechanics is largely an experimental science.  You will be expected to actively participate in all laboratory activities, and to turn in well-written laboratory reports presented in a professional manner.  You may work on the lab data analysis with your colleagues, but the work you turn in must be your own.

Design Project (10%):  One of the great things about engineering is being able to design, build, and test a machine.  In this course, we will design and build positive displacement pumps, and compete against the Mechanical Engineers in the annual Golden Piston Competition!

Midterm Exam (20%):  The midterm exams will be conducted in two parts.  The first part will be an individual exam, open notes, open book. The second part will be a group exam, where you will work with other students to solve problems similar to those in the first part. The second part will also be open notes, open book.

Final Exam (25%):  The final exam will be cumulative.  It will be conducted in two parts, similar to the Midterm Exam.
