PURDUE UNIVERSITY School of Mechanical Engineering ME 309 Fluid Mechanics Spring 2011 Course Web Page Assignments, class information, and scores will be posted on Blackboard Vista: http://www.itap.purdue.edu/tlt/blackboard/ Information presented in lecture or recitation supersedes the information posted on Blackboard. Students are responsible for any information given in lecture or recitation. Textbook Fox, R.W., Pritchard, P.J., and McDonald, A.T., Introduction to Fluid Mechanics, 7th ed., Wiley & Sons. Additional Helpful References Munson, B.R., Young, D.F., and Okiishi, T.H., Fundamentals of Fluid Mechanics, Wiley & Sons. Sabersky, R.H., Acosta, A.J., and Hauptmann, E.G., Fluid Flow: A First Course in Fluid Mechanics, Macmillan. White, F.M., Fluid Mechanics, McGraw-Hill. Van Dyke, M., An Album of Fluid Motion, Parabolic Press. Undergraduate calculus and thermodynamics texts. Course Objectives 1. Develop the ability to identify and classify the various types of flows one may encounter. 2. Develop (from first principles) the control volume formulation of the basic laws with emphasis on conservation of mass and Newtons 2nd law. 3. Apply the control volume formulation of the basic laws to model physical systems. 4. Conduct simple experiments and analyze data. 5. Enhance systematic problem solving skills and sharpen written communication skills through short technical laboratory reports. Course Prerequisites ME 309 must be preceded by differential equations, dynamics, and a first course in thermodynamics. Computer Usage Knowledge of word processing and spreadsheet software will be necessary for laboratory report preparation and some homework assignments. Knowledge of a computer programming language may also be helpful for some assignments. Attendance and Honesty Policy Students are responsible for all material covered during class, including assignments and quizzes. If the instructor is late, students should wait 15 minutes before leaving. In the event of a major campus emergency, course requirements, deadlines, and grading schemes are subject to changes that may be necessitated by a revised semester calendar or other circumstances beyond the instructors control. Campus emergency information can be found on Purdues home page < http://www.purdue.edu >. Students can also sign up for emergency text messages at < http://www.purdue.edu/securepurdue/ >. Students are encouraged to avoid coming to class if they are ill so that they can recover more quickly and avoid infecting their colleagues. The instructor will work with the student to determine the best approach for getting the student caught up on the course material when they return. Students must pre-arrange absences for graded assignments and exams, or submit a documented excuse (e.g., a note from a doctor) if such arrangements cannot be made. The Purdue University Code of Honor is in effect for all students: http://www.purdue.edu/univregs/pages/stu_conduct/code_of_honor.html Students are not allowed to collaborate, talk with one another, or use unauthorized materials on exams. Violation of this policy will result in a failing grade (i.e., a grade of an F) for the course, and be reported to the Office of the Dean of Students.

PURDUE UNIVERSITY School of Mechanical Engineering ME 309 Fluid Mechanics Spring 2011 Grading Policy
Final grades will be determined using the following algorithm. 1. All final scores will be normalized (i.e., divided) by, at most, the largest student final score in the class and multiplied by 100. The value of the normalization score may be smaller than the largest student final score, based on the instructors discretion and the overall course performance. For example, if the largest final score in the class is a 95, all other scores will be divided by a value 95. 2. The final grades will be determined using the following table. 97 score A+ 93 score < 97 A 90 score < 93 A87 score < 90 B+ 83 score < 87 B 80 score < 83 B77 score < 80 C+ 73 score < 77 C 70 score < 73 C67 score < 70 D+ 63 score < 67 D 60 score < 63 Dscore < 60 F 5% Homework a) Collaboration on homework is limited to general discussion of the problems and approaches. Each student must independently complete his/her own written solution to each homework problem. Copying another persons homework or using old or other existing solutions is considered plagiarism. b) Homework must be turned in within the first five minutes of your lecture period on the due date. Homework will not be accepted at the end of the lecture period or in another lecture period. Late homework will not be accepted without an authorized excuse. A c) subset of the assigned homework problems will be graded. You may wish to retain a copy of your homework solution to compare with the posted solution prior to your work being returned to you. d) Homework will be returned in your laboratory preparation session. Graded homework not picked up during the lab prep session will be discarded after one week from when it was first made available for return. e) Homework solutions will be posted on Blackboard. 10% Laboratory a) Refer to the Laboratory Policy and Procedures handout for details concerning the laboratories. 5% Quizzes Short quizzes will be given during many of the lab preparation periods and/or in lecture, and will be based on the material covered in previous weeks. No make-up quizzes will be given. 20% Exam 1: Tu, 15 Feb; 8:00-10:00 P.M.; PHYS112 20% Exam 2: Tu, 22 Mar; 8:00-10:00 P.M.; PHYS112 20% Exam 3: Tu, 19 Apr; 8:00-10:00 P.M.; PHYS112 20% Final: TBD a) All exams will be closed notes and closed book unless otherwise indicated. Formula sheets will be provided with the exams. No material other than the formula sheets are to be used during exams. b) A score of zero will be recorded for a missed exam. Make-up exams will be given only by prior (at least 24 hours before the exam start time) arrangement, or for a documented illness or serious emergency. An oral exam may be given in place of a written exam for those students with an authorized excuse. 1. Homework, laboratory, quiz, and exam re-grades must be submitted within one week of the date the graded document has been made available for return. Re-grades submitted after this deadline will not be considered. Re-grade requests must include a written statement detailing the justification for the re-grade. Note that documents are re-graded from scratch and may result in a score lower than the original score. All assignments submitted for grading, including homework, quizzes, laboratory reports, and exams, must be presented in a straightforward and neat manner. Be sure to include all pertinent information such as coordinate axes, free body diagrams, control volumes, and units. Answers should be clearly indicated. Multiple page assignments must be stapled together. Loose, folded, or paper-clipped papers will not be accepted. Points will be deducted for convoluted or sloppy work. Each homework problem must contain the following header printed in the upper, right corner of each page: Last name, First name ME309 Hwk Assignment * Lecture Section * Lab Section * If this format is not followed, a grade of zero will be assigned. For privacy, scores will not be reported via e-mail or telephone. Scores will be posted using Blackboard Vista.
