Fluid properties Flashcards
The science that deals with the action of forces on fluids at rest and in motion
Fluid Mechanics
Study of fluid at rest
Fluid Statics
Study of fluid in motion
Fluid Kinematics
Study of the effect of forces on fluid motion
Fluid Dynamics
Branch of science concerned with practical application of fluids in motion
Hydraulics
Two forms of fluids
Liquid and Gas
Matter with molecules that freely move and does noy possess any rigidity
Fluids
True or False: Liquids are compressible?
False
The amount of resistance of a fluid to shearing forces.
Viscosity
Ratio of dynamic viscosity of fluid to its mass density
Kinematic Viscosity
Contractive tendency of the surface of a fluid
Surface tension
Movement of liquid through a thin-bore tube
Capillarity
Force exerted by vapor
Vapor pressure
Type of fluid that is both incompresible and have no viscosity
Ideal fluid
Type of Fluid that possesses viscosity, compressibility and surface tension
Real fluid
A fluid in which shear stress is directly proportional to the shear strain
Newtonian fluid
A real fluid that doesn’t follow Newton’s Law of Viscosity
Non-Newtonian fluid
Two types of Non-Newtonian fluids
Time Independent
Time Dependent
Fluid where when viscosity decreases as stress increases
Pseudoplastic fluid
Fluid where viscosity increases as stress is applied
Dilatant fluid
Fluid that doesn’t flow until a critical stress is exceeded
Bingham Plastic
Fluid where there’s a decrease in viscosity with time under constant shear stress
Thixotropic fluid
Fluid where there’s an increase in viscosity as time of stress application increase
Rheopectic fluid
