Calculation of Collision frequency of air particles in International Standard Atmosphere model by Geopotential Height.

Keyword

Collision frequency of air particles,International Standard Atmosphere,Geopotential Height,Temperature Gradient,Gas constant,Gravitational acceleration.

Reference

[1]:Japanese Industrial Standards Committee:『Standard Atmosphere』,JIS W0201-1990.
[2]:International Standard Atmosphere. Wikipedia

Remarks

・When Average velocity of air particles is calculated,all external force is disregarded and following conditions are applied:Thermodynamic equilibrium state,Monoatom perfect gas,Maxwellian Velocity Distribution.
・When Geometric height is calculated,centrifugal acceleration is ignored on this calculation.
