It's always been a dream of mine to build a ship and fly around, visit the planets, etc. When I'm doing something monotonous my mind wanders and I go back to designing my space ship. Every time I get to testing the hull, I draw a blank in the "how much pressure" area.
I seem to remember something from waaay back in high school about the average pressure on earth is around 15 psi. Does that mean I would need 15 psi inside the hull on earth to simulate the forces in space?
p.s. No need to destroy my dream, I know it's only a dream. I'm just trying to be realistic about this dream. (did that make sense? probably not,,,lol)
consider that the pressure in the vacuum of space is about 0 atm, and in anycase you would need no more and no less than about 1 atm inside the cabin.
