PURDUE UNIVERSITY School of Mechanical Engineering ME 30900  Fluid Mechanics  Spring 2019 Course Web Pages Assignments, class information, and grades will be posted on Blackboard: https://mycourses.purdue.edu Information presented in lecture or the lab preparation sessions supersedes the information posted on Blackboard. Students are responsible for all information given to them in lecture and the lab preparation session. We will be using Piazza for class discussion. This system is catered to getting you help quickly and efficiently from classmates, TAs and instructors. Rather than emailing questions to the teaching staff, you are encouraged to post your questions on Piazza: https://piazza.com/class/jqi7185g6y52y2 Piazza should be used only for ME 309-related general discussion. Posting of assignment solution procedures is not allowed, but discussion is encouraged. Textbook Pritchard, P.J., Fox and McDonald’s Introduction to Fluid Mechanics, 9th ed., Wiley & Sons.

PURDUE UNIVERSITY School of Mechanical Engineering ME 30900  Fluid Mechanics  Spring 2019 Computer Usage Knowledge of word processing, spreadsheet software, and basic programming (for example, MATLAB) will be necessary for laboratory report preparation and some homework assignments. Knowledge of other computer programming language may also be helpful for some assignments. Attendance 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 instructor’s control. See the Emergency Preparedness Syllabus Attachment at the end. 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 upon their return. Students must pre-arrange absences for graded assignments and exams, or submit a documented excuse, e.g., a signed note from a doctor indicating that an assignment could not be completed due to illness, if such arrangements cannot be made. Grading Policy Final grades will be determined using the following algorithm. 1. All final scores adjustments are in the discretion of the instructors. 2. Final grades may be normalized (i.e., divided) as needed by, for example, the largest final score in the class and multiplied by 100. The value of the normalization score may be smaller than the largest 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 may be divided by a value ≤ 95. Depending on class performance, scores may also be curved. In all cases the order of students’ scores will be preserved, i.e. students with higher raw scores will have higher normalized or curved scores. 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

PURDUE UNIVERSITY School of Mechanical Engineering ME 30900  Fluid Mechanics  Spring 2019 3. The following categories of grades with the following weights will be used: 5% Homework a) Homework assignments can include a combination of reading assignments, problem solving and computer work. b) Homework assignments will be announced electronically on Blackboard and will be submitted electronically on the course Gradescope site. Homework must be submitted only as a single PDF file. Any other type of file format, or submission of multiple files, will not be accepted, and it will automatically result in a grade of zero for the assignment without exception. Upon uploading your single, legible PDF file, ensure you see a readable preview of it. If this is not the case, your upload has failed. Failed uploads cannot be resubmitted and will result in a grade of zero without exception. Absolutely no late submissions accepted. c) Homework will not be submitted or collected in class, before during or after lecture periods or laboratory sessions. Late homework will not be accepted without an authorized excuse. d) Homework assignments are individual. Collaboration on homework is limited to general discussion of the problems and approaches. All student must independently complete their own written solution to each homework problem. Copying from another person’s solutions, or from a previous course's posted solutions, or from any place on the internet, or from any other existing solutions is considered plagiarism and will result in disciplinary action according to Purdue's policies. e) A subset of the assigned homework problems will be graded. Every student’s lowest two homework scores for the semester will be dropped. 5% Instructor Discretion, Participation and Preparation a) Each instructor may assign this portion of the final grade at his or her discretion. This score will be based on a quantifiable, documented metric. Examples include an attendance record, in-class participation and/or quizzes, and reading quizzes before lectures. Each instructor will specify at the beginning of the semester how this portion of the grade will be determined and how missed assignments will be handled. The process will be clearly communicated to the students and made available either in a written document and/or on Blackboard. b) In-class quizzes may require the use of i>Clicker, hotseat or Replay. Students are expected to have an appropriate device ready for lecture. Devices will be registered during the first week of class. c) Reading quizzes will be given via Blackboard before every class period for which there is a reading assignment listed. Students are responsible for completing the quizzes in the allotted timeframe and by the stated deadline. d) Instructor discretion points are not transferrable between sections.

true in all that I do. Accountable together – we are Purdue.” https://www.purdue.edu/provost/teachinglearning/honor-pledge.html If a student is involved in two or more academic dishonesty incidents, then that student will receive a final grade of “F” for the course. All academic dishonesty incidents will be reported to the Office of the Dean of Students. Incidents under Note 5 below will be treated as academic dishonesty. Assignment re-grades must be submitted within 1 week of the date the graded document has been made available for return. After 1 week, re-grades will not be considered. Re-grade requests must include a written statement with justification for the re-grade. Tests and assignments are re-graded from scratch, which may result in a lower score than the original. 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. If hard copies are accepted, then multi-page assignments must be stapled together; loose, folded, or paper-clipped papers will not be accepted. Likewise, when PDF submissions are expected, poorly scanned or invalid files will not be accepted. Points will be deducted for convoluted or sloppy work. Each page of an assignment must have student’s name and lecture section. For privacy, scores will not be reported via e-mail or telephone. Grades and various scores will be disseminated only via Blackboard. Course materials and commercial web pages: In general, class notes (including answer keys to old exams or homework) are “considered to be ‘derivative works’ of the instructor's presentations and materials, and they are thus subject to the instructor's copyright in such presentations and materials.” As such, they cannot be sold or bartered (for example, on commercial web pages) without express written permission; see also item J in http://www.purdue.edu/studentregulations/student_conduct/misc.html Purdue University is committed to advancing the mental health and well-being of its students.

EMERGENCY PREPAREDNESS SYLLABUS ATTACHMENT

EMERGENCY NOTIFICATION PROCEDURES are based on a simple concept – if you hear a fire alarm inside, proceed outside. If you hear a siren outside, proceed inside. • Indoor Fire Alarms mean to stop class or research and immediately evacuate the building. • Proceed to your Emergency Assembly Area away from building doors. Remain outside until police, fire, or other emergency response personnel provide additional guidance or tell you it is safe to leave. • All Hazards Outdoor Emergency Warning Sirens mean to immediately seek shelter (Shelter in Place) in a safe location within the closest building. o “Shelter in place” means seeking immediate shelter inside a building or University residence. This course of action may need to be taken during a tornado, a civil disturbance including a shooting or release of hazardous materials in the outside air. Once safely inside, find out more details about the emergency*. Remain in place until p...
