% Compute the mass and dimensions of a habitat for astronauts
This function is designed to produce a rough estimate based on crew
consumable consumption and estimates of the needed volume and masses of
appliances and furniture.
The pressure vessel calculation uses hoop stress. Aluminum 6061-T6 is
assumed. For a safety factor increase the pressure p. The radius of the
habitat is fixed. It computes the length based on the crew size.
The numbers in the function are from numerous sources.
Type HabitatMass for a demo.

Form:
HabitatMass; % demo for 4 crew
[m,r,l,s,mEOL] = HabitatMass(nCrew,nDays,p)
