Fludis Flashcards
Fluids
Has the ability to flow
Incompressible Fluids
Fluids with constant volume, non-compressible
Classification of Fluids
Real Fluids
Ideal Fluids
Real Fluids
Have some viscosity
Internal friction among their molecules
Ideal Fluids
No frictional or viscous forces exerted
Properties of Fluids
Compressibility
Viscosity
Density
Capillarity
Surface Tension
Saturation or Vapor Pressure
Compressibility
Change in volume under pressure
Viscosity
Resistance to flow, internal friction.
Density
Mass per unit volume
Capillarity
Liquid rise in narrow spaces.
Surface Tension
Force at liquid-air interface
Saturation or Vapor Pressure
Equilibrium vapor concentration, pressure
Hydrodynamics
Investigation of incompressible and frictionless fluids
Pressure
Force per unit area
Density
Mass per unit volume
