FLUID MECHANICS
CHAPTER 1: INTRODUCTION OF FLUID
1.0 INTRODUCTION OF FLUID
Fluid mechanics is a branch of physics concerned with fluid mechanics and forces
acting on them. Mechanical, civil, chemical, and biological engineering, geophysics,
oceanography, meteorology, astrophysics, and biology are just a few of the fields
where it might be used.
1.1 FLUID CHARACTERISTIC
Fluid mechanics is a study of the behavior of fluids (liquids or gases) either at rest
or in motion. The study of fluid at rest is called fluid statics. The study of fluid in
motion, where pressure forces are not considered, it is called kinematics and if the
pressure is considered for the fluid in motion, it is called fluid dynamics. An
understanding of the properties and behavior of fluids is very importance in
engineering. A fluid is a state of matter that yield to sideways or shearing forces.
Liquid and gas are both fluids. Fluid statics is the physics of stationary fluid.
