B Air tank PSI and cubic feet calculation help please

Click For Summary
To determine the volume of air at 100 psi in a 1 cubic foot tank pressurized to 5000 psi, the ideal gas law can be applied. The relationship between pressure and volume indicates that as pressure increases, the volume of gas decreases proportionally. At 5000 psi, the tank contains significantly more air than it would at 100 psi due to compression. Calculating the exact volume at 100 psi requires converting the pressures into a common unit and applying the formula for gas laws. Understanding these principles is essential for accurate air tank calculations.

If I have a air tank that is 1 cubic feet with the pressure gauge at 0 and I pump in air to 5000 psi how many cubic feet of a 100 psi would be in that tank? Any help would be appreciated

Hello, I'm joining this forum to ask two questions which have nagged me for some time. I am in no way trolling. They both are presumed obvious, yet don't make sense to me. Nobody will explain their positions, which is...uh...aka science. I also have a thread for the other question. Yes, I'm questioning the most elementary physics question we're given in this world. The classic elevator in motion question: A person is standing on a scale in an elevator that is in constant motion...
