Aerostatics

The aerostatic is as a branch of fluid statics, the doctrine of the unmoved, in particular the flow-free, gas. The aerostatic deals with the density distribution mainly in the air. One of its applications is the barometric formula.

Some areas of work Aerostatics are:

• The kinetic theory of gases
• Gas pressure
• The air pressure measurement (using a barometer )
• The gas density,
• The composition of the soil air
• The partial pressure in gas mixtures
• Variations in air pressure
• Composition of the mountain air
• The cross section of the atmosphere

Missiles, whose density is less than that of air, were referred to in the 20th century as Aerostat. So this was a generic term for balloons and airships.
