3. Course Objectives

This class provides students with an introduction to principal concepts and methods of fluid mechanics. Topics covered in the course include pressure, hydrostatics, and buoy- ancy; open systems and control volume analysis; mass conservation and momentum conservation for moving fluids; viscous fluid flows, flow through pipes; dimensional analysis; boundary layers, and lift and drag on objects. Students will work to formulate the models necessary to study, analyze, and design fluid systems through the application of these concepts, and to develop the problem-solving skills essential to good engineering practice of fluid mechanics in practical applications.

4. Prerequisites & require

1.Thermodynamics (MECH250).
2.Elementary ordinary differential equation (MATH130).

5. Grading

There will be two closed-book midterm exams (40% (20%+ 20%)) and a closed- book final exam (30%). Attendance at regular classes will not be checked. However, three-to-five 10-minute quiz sessions (10%) will be held randomly without a priori notice and a failure taking the quiz will result in reduction of grade points per quiz in lieu of the attendance check (10%). There will be homework sets, but they will not be collected. Instead, about 70% of the problems in the exams and quizzes will be selected from the homework sets. The remaining 10% of your grade will be determined by reports on experiments which will be provided as a part of the schedule of the course.
