Set of quasilinear hyperbolic equations governing adiabatic and inviscid flow/Navier-Stokes Eq's reduce to these when viscosity & thermal conductivity are zero | |

Adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface | |

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) | |

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 | |

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 | |

Process in which atoms, molecules or ions enter some bulk phase (gas, liquid or solid material) & are taken up by the volume of substance | |

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 | |

Instrument w/one closed end containing a vacuum that uses a column of liquid to measure atmospheric pressure | |

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 | |

Chaotic fluid flow which is normally treated statistically due to irregularity of flow | |

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 | |

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) | |

Compounds that lower surface tension between 2 liquids or a liquid & solid/detergents, emulsifiers, foaming agents, dispersants/hydrocarbon w/hydrophilic heads & hydrophobic tails | |

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 | |

Tendency of dissimilar particles or surfaces to cling to one another | |

Arises from friction between neighboring particles/measure of a fluid's resistance to gradual deformation by shear stress or tensile stress | |
