Study Notes
Fluid Mechanics
- Branch of fluid mechanics concerned with relations between velocities, accelerations, and forces exerted on fluids in motion: fluid dynamics
- Study of mechanics of fluids at rest: fluid statics
- Ideal or perfect fluid: a fluid with zero viscosity, incompressible, and inviscid
Characteristics of Fluids
- Occupy all the space in which they are contained
- Show little resistance to change in form or volume
- Examples: liquids and gases
Thermodynamics
- Closed system: a system that does not exchange matter with its surroundings
Fluid Statics and Fluid Kinematics
- Fluid statics: study of fluids at rest
- Fluid kinematics: study of fluids in motion
Hydrodynamics
- Study of the mechanics of fluids in motion
- Concerned with the relations between velocities, accelerations, and forces exerted on fluids in motion
Difference from Solids
- Fluid mechanics differs from the mechanics of solids due to the ability of fluids to flow and change shape in response to forces
