Aerostatics

Encyclopedia : A : AE : AER : Aerostatics

Aerostatics is the study of gases that are not in motion. The corresponding study of gases in motion is aerodynamics. It is a subfield of fluid statics that focuses on gases.

Aerostatics studies density allocation, especially in air. One of the applications of this is the barometric formula.

Fields of study include:

The kinetic theory of gases
Gas pressure
Pressure measurement
Gas density
Gas diffusion in soil
Partial pressures in gas mixtures
Atmospheric pressure fluctuation
Composition of mountain air
Cross-section of the atmosphere

A balloon or airship, which uses the principles of aerostatics to float, is known as an aerostat.
