Why do I have to study it? Why should I want to study it? What are the applications of fluid mechanics? Fluid includes liquids and gaseous. Fluid mechanics deals with the behavior of fluids at rest and in motion. Knowledge and understanding of the basic principles and concepts of fluid mechanics are essential to analyze any engineering system, such as internal combustion engines, gas turbines, water turbines, etc, in which a fluid is the working medium. In addition, fluid mechanics can be classified into two categories: fluid statics and fluid dynamics. Fluid statics deals with the pressure and resultant forces when the fluid is at rest. While the fluid dynamical behavior and the flow induced forces are the scopes of fluid dynamics. Because the design of all fluid machinery including pumps, fans, blowers, compressors, and turbines clearly requires knowledge of the basic principles of fluid mechanics, therefore mechanical engineering students have to study it. In order to understand the detailed behavior of the flowfield, the conservation of mass, momentum, and energy that governs the flowfield must be fully understood. Fluid mechanics (I) will introduce the governing equations and their applications. The objective of this course is to provide students with the
knowledge of basic laws such as the conservation of mass, Newton s second law of motion, the principle of angular momentum, and the first and second laws of thermodynamics governing the fluid motion. When students finish the fluid mechanics course, we expect them to be able to apply the governing equations to a variety of problems, including those they have not encountered previously.
