I have 2 identical pressure vessels P1 and P2, exactly 1000 cc each. I pressurise them both to exactly ##1000 lbs/in ^2##. I place one on a spaceship and keep the other beside me. The ship blasts off.
As the ship whizzes past me, as a result of length contraction, I see that the vessel on the spaceship is no longer 1000cc, but some value less than 1000cc, as its length has contracted but its width remains the same. Therefore I must conclude that the pressure in the vessel on the spaceship is higher than the pressure in the vessel at rest wrt to me...agree?
If I remotely measure the dimensions of the vessel on the spaceship I can figure out precisely what the pressure is in the spaceship vessel
