Fluid Mechanics Principles and Applications MET 3101 INSTRUCTOR: Dr. Norman Russell: Phone – 678 915 5480; Office Q226. E - mail [email protected] Office hours will be posted and noted in class. Students with disabilities who believe that they may need accommodations in this class are encouraged to contact the counselors at ATTIC as soon as possible to ensure that such accommodations are implemented in a timely fashion. The educate.spsu.edu/faculty website will be used to communicate information on the syllabus, test schedules, assignments, and topic schedules. The prefix “afm” will designate the appropriate information. In addition, e-mail will be used to present current information on class activities. Students will adhere to the guidelines in the Catalog in reference to “Academic Dishonesty”. Prerequistes: ENGR 2214, MATH 2253,TCOM 2010 A study of Fluid Mechanics fundamentals in applications of hydrostatic forces, pumping systems, fluid power, momentum transfer, external flow, and open channel flow. Handson laboratory exercises demonstrate lecture topics. Course Outcomes Students will be able to do the following: 1. Determine forces on submerged surfaces in the design of weirs, dams, tanks, etc. Determine the buoyant forces acting on an object as a function of fluid and solid properties. 2. Apply the general energy equation to pumping systems to determine important operational properties: head, flow, efficiency, cavitation potential. Apply this information in the selection of appropriate system components (pump, pipe, valves, and fittings) to accomplish a task. 3. Evaluate the equipment selection and operation of a hydraulic or pneumatic system for a specific fluid power task. 4. Determine the energy transfer between a flowing fluid and solid surfaces in turbines. 5. Apply empirical equations for the determination of flow in open channels. 6. Apply external flow concepts to calculate drag coefficients for a range of geometric shapes to understand the effects of streamline separation on drag. 7. Prepare laboratory reports using designated format. Course Topics 1. Introduction – a brief description of key concepts and applications.

Laboratory work will be performed in groups and individual reports are required. Students must participate in collecting all information used in a report. Reports are due one week after a lab is performed, unless notified by the Instructor. Late reports will receive reduced credit. NO LAB REPORTS WILL BE ACCEPTED OFR CREDIT DURING THE LAST WEEK OF A SEMESTER. Text: Applied Fluid Mechanics, 6th Edition, Robert Mott. Credits: Three or four tests – 60%; Exam – 20%; Lab Reports 20%. Students must achieve passing grades in both the lecture and laboratory portions of MET 3101.
