Density

Top Articles

Relative density - Relative density (also known as specific gravity) is a measure of the density of a material. It is dimensionless, equal to the density of the material divided by the density of water (or, sometimes used for gases, of air).

Density altitude - Density altitude is the altitude in the International Standard Atmosphere at which the air density would be equal to the actual air density at the place of observation. "Density Altitude" is the pressure altitude adjusted for non-standard temperature.

Nuclear density - Nuclear density is the density of the nucleus of an atom, about 10^18 kg/m³; neutron stars reach this density. Nuclear density is often applied to situations where very high, or nuclear densities occur.

Local-density approximation - The local-density approximation, (LDA), is a density functional model in physics, which approximates the electron correlation energy with respect to the local electron density. In this sense, local means that, within the LDA model, the electron correlation at any point in space is a function of the electron ...
