The Surface Pressure of an object is the force per unit area that the object's atmosphere exerts on its surface.
Property Details[ | ]
Location[ | ]
The Surface Pressure property is located in the Atmosphere section of the Surface tab of the object's properties panel. This section is only visible for Terrestrial Planets.
Units[ | ]
Surface Pressure can be viewed and edited using the following units:
- Standard atmosphere (atm) = 101325 Pa
- Bar (bar) = 100000 Pa
- Kilopascal (kPa) = 1000 Pa
- Millibar (mbar) = 100 Pa
- Pascal (Pa) is the SI unit for pressure.
Simulation Effects[ | ]
Atmosphere Mass[ | ]
The Surface Pressure is related to the atmosphere mass, Matmo, and radius of the object, R, and the surface gravity, gs, of the object by the following equation:
Surface Pressure will determine the Boiling Point and Freezing Point of water on the surface of an object.
