Course title
Basic Fluid Mechanics

YOSHIHARA Shouichirou
Course description
It is very important to understand thermo-fluid transport phenomena in the physical phenomena of nature. For example, there are many machines that use thermal fluids around us, such as aeroplanes moving in the air, pipe materials transporting fluids, petrol and diesel engines, and so on. Therefore, in fluid mechanics, students learn the basics of the principles and principles of viscosity of fluids, forces acting on materials in fluids, momentum and energy conservation laws of fluids, and the concept of phenomena of fluids flowing in pipes, with specific examples of application.
Purpose of class
The purpose of this course is as follows.
1. To master the basics of fluid mechanics, which is the fundamental theory of "design engineering".
2.To acquire the ability to apply this theory.
Goals and objectives
  1. To understand the basics of fluid mechanics and be able to explain basic theories and phenomena.
  2. In fluid mechanics, be able to explain basic theorems such as the continuity formula and Bernoulli's theorem.
  3. To explain the phenomenon of flow and its effects.

Evaluation method and criteria
There will be a report (20 points), a mid-term examination (40 points) and a final examination (40 points), for a total of 100 points. The report will be divided into two parts.
Of the 100 points, 60 points will be considered a passing grade. The standard of passing level is to be able to calculate and understand the meaning of various quantities of fluid mechanics, to understand the meaning of the similarity rule and Bernoulli's theorem, and to be able to calculate various quantities of flow in a circular tube.
