* Density altitude is the altitude corrected for non-ISA International Standard Atmosphere atmospheric conditions.

Density and pressure decrease smoothly with altitude, but temperature ( red ) does not.

* 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, or, in other words, the height when measured in terms of the density of the air rather than the distance from the ground.

" Density Altitude " is the pressure altitude adjusted for non-standard temperature.

Density altitude can be calculated from atmospheric pressure and temperature ( assuming dry air ).

In 1974 – 75, Lee published several papers on " A New Form of Matter in High Density ", which led to the modern field of RHIC physics, now dominating the entire high energy nuclear physics field.

Density is an intensive property in that increasing the amount of a substance does not increase its density ; rather it increases its mass.

The transport mechanism ( Low Density Cholesterol or High Density Cholesterol particles ) varies, and not only in density.

SWP Microcomputer Products of Arlington, TX ( formerly Software Publishers ) provided the Bigboard Dual Density upgrade, which provided both hardware and software to allow the Big Board I to use dual density formats on its drives.

** Density estimation is the construction of an estimate of a probability density function

Density based flow, however, occurs when liquefaction of sediment during transport causes a change to the density of the fluid.

Density, Bulk Density, or Wet Density,, are different names for the density of the mixture, i. e., the total mass of air, water, solids divided by the total volume of air water and solids ( the mass of air is assumed to be zero for practical purposes ):

Buoyant Density,, defined as the density of the mixture minus the density of water is useful if the soil is suberged under water:

Sorting by Size and Density: Most fine coffee goes through a battery of machines that sort the coffee by density of bean and by bean size, all the while removing sticks, rocks, nails, and miscellaneous debris that may have become mixed with the coffee during drying.

Amsterdam Density Functional ( ADF ) is a program for first-principles electronic structure calculations that makes use of density functional theory ( DFT ).

Equivalent Circulating Density ( when forward circulating ) is defined as the apparent fluid density which results from adding annular friction to the actual fluid density in the well.

Density is not measured directly but is calculated from measurements of temperature, pressure and humidity using the equation of state for air ( a form of the ideal gas law ).

In 2001, Plum Creek at their Medium Density Fiberboard facility completed the installation of a biofilter, a new air emission treatment technology.

Dry Density,, is the mass of solids divided by the total volume of air water and solids:

Density is the ratio of bond and abrasive to air space.
