Specifications for Large Ship

[SpaceNut]

seems that we can migrate the fluxbb discussions to this format.

[RobertDyck]

Atmosphere specification, for large ship and Mars habitats:
2.7 psi O2
3.5 psi N2
1.148 psi Ar
Total: 7.348 psi total = 1/2 Earth atmospheric pressure at sea level

Spacesuit: 3.0 psi pure oxygen

Note: maximum nitrogen in higher pressure environment for decompression with zero pre-breathe time is total pressure of lower pressure x 1.2. So for suit with 3.0 psi, max nitrogen if hab = 3.0 x 1.2 = 3.6 psi. Pressure is reduced to 3.5 as a safety measure.

Also note: once humans start to breathe, some O2 will be converted to CO2, and water will be added as humidity. Water source is moisture from lungs via exhaled breath, and sweat.

Metric:
18.615 kPa O2
24.131 kPa N2
7.915 kPa Ar
Total: 50.661 kPa

Spacesuit: 20.684 kPa O2
Round metric figure for O2 and N2 to 2 significant figures. 3 at most.

This deep space vessel is defined by a set of specifications laid down by RobertDyck, Moderator of NewMars.com/forums.

Posts in this topic will be about those specifications.
