Liquid Viscosity Nina Clavio Argela OlbesPowerPoint Presentation: INTRODUCTIONViscosity: Viscosity - Migration of linear momentum along a velocity gradient. - Fluid’s resistance to flowViscosity: Viscosity 2 types: dynamic/ absolute kinematicDynamic or Absolute: Dynamic or Absolute Measure of internal resistance Tangential force per unit area required to move one horizontal plane with respect to another at a velocity maintained at a distanceDynamic or Absolute: Dynamic or AbsoluteDynamic or Absolute: Dynamic or Absolute Τ = ɳ dc/ dy where: Τ = shearing stress ɳ = dynamic coefficientKinematic: Kinematic ratio of absolute or dynamic viscosity to density a quantity in which no force is involved obtained by dividing the absolute viscosity of a fluid with it's mass densityKinematic: Kinematic v = ɳ / ρ where: v = kinematic viscosity Ρ = densityViscosity: Viscosity 2 factors: Intermolecular forces of attraction (strong bonds = high viscosity) Temperature (high temp = low viscosity) Pressure (high pressure = high viscosity) Velocity (high velocity = low viscosity)Viscosity: Viscosity Other factors: Size of molecules (bigger molecules, high viscosity) Shape of molecules (oval and disk-like molecules, high viscosity) Note: not generally applicableOstwald Viscometer: Ostwald ViscometerPoiseuille Equation: Poiseuille EquationPowerPoint Presentation: Methodologymethodology: methodology clean viscometer with chromic acid sol’n , soap and distilled water 5.0 mL distilled water into viscometer Water bath (15 mines)methodology: le methodology measure as liquid flows from upper to lower mark You do not have the permission to view this presentation.
