In this course, fundamental concepts of fluid mechanics will be introduced. Specific topics shall cover basic properties of fluids, description of fluids at rest and in motion, kinematics of fluid motion, flow analysis using control volumes and differential methods, and dimensional analysis and modeling. If time is available, pipe flow and external flow with boundary layers shall be introduced. Students can study with the aid of various resources such as fluid videos and online materials.

We will cover the following topics in basic FM course:

Properties of fluis (liquid, gas) & fluid statics[Ch. 1, 2, 3]
Governing equations—integral form [Ch. 4, 5]
Governing equations—differential form [Ch.9]
Control volume analysis of flow system [Ch.6, Ch.13]
Dimension analysis and similitue [Ch. 7]
Flow over bodies [Ch.11]
-------------Midterm-------------------------------------
Analytic solution [Ch. 9]
Approximate solution: Inviscid (Potential) flow [Ch. 10A]
Approximate solution: Boundary layer theory [Ch. 10B]
Compressible flow [Ch. 12]
-------------Final---------------------------------------

Attend lectures; review lecture notes and study textbook; take quiz and exams.
