Barometric formula
The barometric formula defines atmospheric pressure dependence from altitude.
where:
- p0 - pressure on Earth surface
- M - molar mass of Earth's air
- g - gravitational acceleration
- R - universal Gas constant
- T - air's absolute temperature
let's consider:
p0 = 101325 Pa
M = .029 kg/mol
R = 8.3145 J/(mol*K)
T = 273 K
