Fluid Mechanics-Fluid Properties - Part 1.ppt
- 1. Fluid Mechanics INTRODUCTION Mr.S.V.Kumbhar, Assistant Professor, Automation and Robotics, Sharad Institute of Technology, College of Engineering, Yadrav
- 2. Background and introduction • Physical Characteristics of Fluids • Distinction between Solids, Liquids, and gases • Flow Classification • Significance of Fluid Mechanics • Trends in Fluid mechanics
- 3. Physical Characteristics of Fluids:- Statics Dynamics RigidBodies (Thingsthatdonotchangeshape) DeformableBodies (Thingsthatdochangeshape) Incompressible Compressible Fluids Mechanics Branch of Mechanics
- 4. Physical Characteristics of Fluids • Fluid mechanics is the science that deals with the action of forces on fluids. • Fluid is a substance • The particles of which easily move and change position • That will continuously deform Contd…..
- 5. Distinction Between Solids, Liquids & Gases • A fluid can be either gas or liquid. • Solid molecules are arranged in a specific lattice formation and their movement is restricted. • Liquid molecules can move with respect to each other when a shearing force is applied. • The spacing of the molecules of gases is much wider than that of either solids or liquids and it is also variable.
- 6. Flow Classification The subject of Fluid Mechanics • Hydrodynamics deal with the flow of fluid with no density change, hydraulics, the study of fluid force on bodies immersed in flowing liquids or in low speed gas flows. • Gas Dynamics deals with fluids that undergo significant density change
- 7. Significance of Fluid Mechanics:- Flicking on a light switch Moving of Rivers Driving cars The flow of bloods through our veins Coastal cities discharge their waste Air pollution And so on so forth … Trends in Fluid Mechanics • The science of fluid mechanics is developing at a rapid rate.
