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)
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
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
U'shaped instrument w/both ends open that uses a column of liquid to measure pressure of something (usually gas) inside a container
Unit of pressure defined as 101,325 Pa
Law of hydraulics used to study aquifers/fluids move from areas of higher pressure to areas of lower pressure
Compounds that lower surface tension between 2 liquids or a liquid & solid/detergents, emulsifiers, foaming agents, dispersants/hydrocarbon w/hydrophilic heads & hydrophobic tails
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
Fluid with no resistance to shear stress
Study of mechanical properties of fluid in applied science or engineering
Tendency of dissimilar particles or surfaces to cling to one another
Instrument w/one closed end containing a vacuum that uses a column of liquid to measure atmospheric pressure
Unit of pressure defined as 1/760 standard atmospheres
Unit of pressure used when inflating tires
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)
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
Differential equations arising from Newton's 2nd law that describe the motion of fluid substances/3-D version is a Millenium problem
Set of quasilinear hyperbolic equations governing adiabatic and inviscid flow/Navier-Stokes Eq's reduce to these when viscosity & thermal conductivity are zero
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
SI unit for pressure/equal to 1 N/m^2
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
The pressure exerted anywhere in a confined imcompressible fluid is transmitted equally in all directions throughout the fluid
Defined as force divided by area
Arises from friction between neighboring particles/measure of a fluid's resistance to gradual deformation by shear stress or tensile stress
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
Tendency of similar or identical particles/surfaces to cling to one another
Adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface
Dimensionless quantity used to predict similar flow patterns in different fluid flow situations/introduced by Stokes/ratio of inertial forces to viscous forces
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
