Newtonian fluid
Viscosity only changed with temperature
Specific heat capacity
Energy required to heat 1kg of material by 1K
Specific latent heat of fusion
Energy required to change 1kg of a material from solid to liquid without change in temperature
Specific latent heat of vaporisation
Energy required to change 1kg of material from solid to liquid to gas without change in temperature
Theopectic liquids
Become more viscous when shaken, synovial liquid
Shear thinning liquids
Viscosity decreases with shear strain like paint and whipped cream
Shear thickening liquids
Viscosity increases with shear strain
Internal energy
The sum of potential and kinetic energy
Dilatant liquids
Viscosity increases with rise of shear stress like corn flour mixed with small water
Bernoulli principles
At any point in a tube through which fluid is flowy, the sum of the pressure energy and the potential energy and kinetic energy constant
Laminar flow
Layers of fluid slide over each other
Viscosity
A fluid resistance to flow
Turbulent flow
Layers are disrupted and eddies are formed/seen
Ductility
The ability of material to be formed by drawing into new shapes
Malleable
Ability of material to be shaped by compression and be hammered into shape
Brittleness
Tendency of mater to fracture under stress, can’t undergo plastic flow
Elastic hysteresis
Occurs in material like rubber, when internal friction between larger molecules dissipates energy producing heat
Yield point
The point where the start of plastic flow causes a change of slope
Fatigue
Occurs when relatively low levels of stress if there’s repeated applied force
