Course description
The course is compulsory for the second year students at the department of mechanical engineering. In this lecture, the students will learn the fundamentals of fluid mechanics. The lecture consists of basic properties of fluids, static and dynamical aspects of fluids. In addition, dimensional analysis will be taught with examples.
Purpose of class
1.To learn the basic knowledge on fluid properties (continuity, density, viscosity, and surface tension).
2.To learn the fundamentals of fluid statics (absolute/gauge pressure, manometers, Pascal’s law, pressure distribution, forces acting on a solid surface immersed in liquid, buoyancy, Archimedes' principle).
3.To learn the fundamentals of fluid dynamics (different types of flows (steady/unsteady, viscous/inviscid, laminar/turbulent), stream/path/streak lines), flowrate and hydrodynamic conservation laws (continuity equation, Euler’s equation of motion, Bernoulli’s theorem, Torricelli's law, Pitot/ Venturi tubes, momentum theorem).
4.To learn the dimensional analysis (basic/derived quantities, Buckingham’s pi-theorem, similarity parameters).
5.To learn the applications of the above concepts to fluid flow problems.

Evaluation method and criteria
Evaluation method and criteria HW assignments (Including preparation and review of the class.) Amount of Time Required
The final score is evaluated based on practice (10%), assignments (35%), intermediate exam (20%) and final exam (35%). Credit will be given only when the score is equal or over 60% out of 100 % in total. Successful credit acquisition requires the following all the conditions to be satisfied. The student is capable of 1. understanding the concept of fluid and to be able to explain the properties of fluid, and besides, 2 understanding the hydrostatic forces acting on a solid surface immersed in liquid and calculating them in a specific situation, and besides, 3. understanding the basic equations of the conservation laws (continuity equation, Euler's equation, Bernoulli's theorem and momentum theorem) and applying them in a specific problem, and besides, 4. understanding the concepts of dimensional analysis and applying it in a specific situation.

Textbooks and reference materials
The following textbooks are available online for use in this lecture. The students can access the electronic book data via ProQuest Ebook Central through the SIT library.
1. “Introduction to Fluid Mechanics (5th edition)”, by William S. Janna, Chapman and Hall/CRC (2015)
2. “Fluid Mechanics and Machinery” C.P. Kothandaraman , and R. Rudramoorthy, New Academic Science (2011)
The students may refer to other supplement textbooks such as: “A Physical Introduction to Fluid Mechanics” by Alexander J Smits, Wiley (1999). Most of introductory textbooks on fluid mechanics or fluid dynamics would be helpful for the students to understand the course contents. (Those who have difficulties for reading in English can refer any textbook written in their own language on hydrodynamics (such as Nagare-gaku) or fluid mechanics (such as Ryutai-rikigaku).)
