Hydrodynamics 1

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.

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.

1. To understand the concept of fluid and to be able to explain the properties of fluid.
2. To understand the hydrostatic forces acting on a solid surface immersed in liquid and to be able to calculate them in a specific situation.
3. To understand the basic equations of the conservation laws (continuity equation, Euler’s equation and Bernoulli’s theorem, momentum theorem) and to be able to apply them in a specific problem.
4. To understand the concept of dimensional analysis and to be able to apply it in a specific situation.

The final score is evaluated based on practice (10%), assignments (40%), intermediate exam (20%) and final exam (30%). 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.

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).)

Prerequisite knowledge
basic knowledge on mathematics (linear algebra, calculus, vector analysis) and physics (dynamics)
(The prerequisite knowledge will not be taught in this class. Those who do not have the prerequisite knowledge are advised not to enroll in this course.)

Preparation
The students are requested to learn the basic ideas on the content before the lecture for understanding. The students are encouraged to solve problems for improve their understandings of the subject. Homework assignment must be submitted online via scomb system.

Advice
- This course is premised on the regular attendance of students in the lecture.
- The students are expected to be involved in the lecture, practice and homework assignments.
- The students should regularly check the scomb system for homework assignments every week after the class.
