My current story is set inside a hollowed out dwarf planet (i.e. Ceres) with an artificial gravity generating "mesh" within the shell. This Gravity Mesh can generate a gravitational field that can be modified, anywhere between 0.01g and 10g in strength.
On Earth, sea level air pressure is 101.33 Kpa, and the Armstrong limit (the pressure at which water boils at human body temperature [37 degrees celsius]) is 6.26 kPa, which usually occurs at around 19,000 meters. The elevation at which humans usually need supplemental oxygen is 4,500 meters, which has an air pressure of 57.73 kPa.
What I would like to know is, how would changing the strength of the gravitational field affect the air pressure.
What would the air pressure be at "sea level" at 2g? 5g? 10g? 0.01g?
Would the different gravities alter the elevation at which humans would need supplemental oxygen? If so, how?
At what elevation would the Armstrong limit occur at these different gravities?
What is the highest gravity before humans breathing the air would go into a state of hyperoxia (too much oxygen)?
Assume the atmosphere consists of a standard nitrogen/oxygen mix with Earth-like stats at 1g.
