Unit of pressure defined as 101,325 Pa
Differential equations arising from Newton's 2nd law that describe the motion of fluid substances/3-D version is a Millenium problem
Layer of fluid in immediate vicinity of bounding surface where effects of viscosity are significant (i.e. atmospheric air near ground/air close to wing on aircraft)
Metric but not SI unit of pressure defined by IUPAC as exaclty equal to 100,000 Pa/equal to atmosphereic pressure on Earth at sea level
Tendency of dissimilar particles or surfaces to cling to one another
Curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension/can be concave or convex
Process in which atoms, molecules or ions enter some bulk phase (gas, liquid or solid material) & are taken up by the volume of substance
Unit of pressure defined as 1/760 standard atmospheres
Arises from friction between neighboring particles/measure of a fluid's resistance to gradual deformation by shear stress or tensile stress
Law of hydraulics used to study aquifers/fluids move from areas of higher pressure to areas of lower pressure
Particular case of Bernoulli's principle/speed of a fluid through a hole at base of tank filled to height h = speed of a drop free-falling from h
The upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces
U'shaped instrument w/both ends open that uses a column of liquid to measure pressure of something (usually gas) inside a container
Adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface
Defined as force divided by area
Study of mechanical properties of fluid in applied science or engineering
Instrument w/one closed end containing a vacuum that uses a column of liquid to measure atmospheric pressure
Dimensionless quantity used to predict similar flow patterns in different fluid flow situations/introduced by Stokes/ratio of inertial forces to viscous forces
Unit of pressure used when inflating tires
Contradiction discovered in 1752 stating that for incompressible & inviscid potential flow the drag force is zero on a body moving w/constant velocity relative to the fluid
Reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe/named for Italian physicist (1746-1822)
Set of quasilinear hyperbolic equations governing adiabatic and inviscid flow/Navier-Stokes Eq's reduce to these when viscosity & thermal conductivity are zero
Tendency of similar or identical particles/surfaces to cling to one another
Fluid with no resistance to shear stress
The pressure exerted anywhere in a confined imcompressible fluid is transmitted equally in all directions throughout the fluid
Manometric unit of pressure still used in medicine & meteorology/almost exactly the same as 1 Torr/pressure generated by 1 mm column of a particular liquid metallic element
Chaotic fluid flow which is normally treated statistically due to irregularity of flow
Compounds that lower surface tension between 2 liquids or a liquid & solid/detergents, emulsifiers, foaming agents, dispersants/hydrocarbon w/hydrophilic heads & hydrophobic tails
Fluids equation that states that an increase in the speed of a fluid leads to a decrease in pressure or in the fluid's potential energy/pres. + 1/2 dens. x v^2 + dens. x g x y = C
SI unit for pressure/equal to 1 N/m^2
Property of liquids that forces it into the shape that minimizes surface area/allows it to resist external force/measured in force/unit length or energy/unit area
