The Granular Volcano Group
Computational Atmosphere

Values at sea-level (altitude zero meter), we have:

Temperature = 288.15 K = 15.15 °C
Air density = 1.225 kg/m3
Atmospheric Pressure = 101327.27 Pa = 1.013 x 105 Pa = 1 atm

Select unit system:

English System of Units (retarded and prehistoric)

International System of Units (recommended because of its modernity and its efficiency)

Inputs:

Altitude:
Speed:
Reference Length:

Results:

Temperature
Density
Pressure
Speed of Sound
Viscosity
Mach Number
Dynamic Pressure
Critical Cp
Vacuum Cp
Reynolds Number
Laminar Cf
Turbulent Cf
