  • Potential density — The potential density of a fluid parcel at pressure P is the density that the parcel would acquire if adiabatically brought to a reference pressure P {0}, often 1 bar (100 kPa). Whereas density changes with changing pressure, potential density of …   Wikipedia

  • potential density —    1. The density of a unit of water after it is raised by an adiabatic process to the surface, i.e., determined from in situ salinity and potential temperature [22].    2. Density that would be reached by a compressible fluid if it were… …   Lexicon of Cave and Karst Terminology

  • Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… …   Wikipedia

  • Density (disambiguation) — Density and dense usually refer to a measure of how much of some entity is within a fixed amount of space. Types of density include: In physics, density of mass: Density, mass per volume Area density or surface density, mass over a (two… …   Wikipedia

  • Potential vorticity — (PV) is a quantity which is proportional to the dot product of vorticity and stratification that, following a parcel of air or water, can only be changed by diabatic or frictional processes. It is a useful concept for understanding the generation …   Wikipedia
