CH 7 Definitions Flashcards
Define Fluids
Materials that have no fixed shape and are free to flow, such as liquids and gases
Define Particle Theory Of Matter
A theory that explains what matter is made of and how it behaves
Define Laminar Flow
A smooth pattern of flow
Define Turbulent Flow
An irreguar, mixing flow pattern
Define Eddy
An area of slower-moving fluid that occurs behind an obstacle
Define Streamlined
A smooth shape designed to decrease resistance to fluid flow
Define Flow Rate
A measure of how quickly fluids move; measured in a volume per unit time (for example, L/s)
Define Viscosity
A measure of how easily a fluid’s particles are able to slide past one another
Define Cohesion
A measure of how strongly the particles of a fluid attract each other
Define Surface Tension
The strong attraction among the particles that form the surface of a liquid
Define Adhesion
The attraction between the particles of one substance and the particles of another substance
Define Fluid Mechanics
The study of fluids and how they behave when at rest and when moving
Define Fluid Dynamics
A part of the study of fluid mechanics concerned with how fluids move
Define Aerodynamics
A part of fluid dynamics concerned with how gases move
Define Hydrodynamics
A part of fluid dynamics with how liquids move
