how is the pressure on a surface lets say a square centimeter, at a specific altitude and speed calculated?
I plan to launch a rocket to low earth orbit with a spring loaded air inntake that i want to close at a certain altitude.

You required a pitot tube to do that. Every jetliner/plane has one on board. So read up on the pitot tube as its applications.
Also the pressure varies logaritmically with height since there are fewer air molecules as the height increases
log Pbase10= 5-(h/15500) where P is in pascals and h in metres
So you can calculate the pressure if you know the height

I would have to ask my dad, who's an aeronautical engineer, because I don't have that info handy.
'Nuff said?
