This course focuses on fluid motion, theories of which need to be extended from the mathematical expressions founded on solid-state physics. Through this series of lectures and exercises, students will learn the most fundamental and important mathematical or experimental expressions in the field of fluid dynamics, including equations of motion for fluids and their derivations, definitions of laminar and turbulent flows, and practical formulas for pipelines or open channels. The present course is comprised of 2 parts in order to effectively include all the essences in a single course of lectures. It begins with Part 1 (1st to 7th classes) and follows by Part 2 (9th to 15th classes) which cover theories of perfect fluids, theories for viscous fluid, and practical fluid problems and their solution using the formulas derived.
By the end of this course, students will be able to understand:
1) Dynamics, force and energy of fluids and their expressions in physics
2) Distinctive properties of fluids such as compressivity and viscosity
3) Regimes in fluids, laminar and turbulent flows, and their theories and experimental expressions
4) Fluid motions in pipe or open channels and their theories and experimental expressions
perfect fluid, viscous fluid, laminar flow, turbulent flow, equation of continuity, Euler equations of motion, Navier-Stokes equations, Bernoulli's principle, pipe flow
|Intercultural skills||Communication skills||✔ Specialist skills||Critical thinking skills||Practical and/or problem-solving skills|
Towards the end of the course, students are given exercise problems to solve related to the lecture given each session. To prepare for classes, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.

A mandatory textbook is not designated. A handout will be given at each class.
The following textbooks are recommended, though not necessarily limited:
D. Elger et al. “Engineering Fluid Mechanics”, Wiley ISBN: 978-1118-318751
