How much space does 10lb of air take up?
Atmospheric pressure at sea level is 14.4 pounds per square inch. That would be 2073.6 pounds per square footbut if you’re looking for only the area covered by 10 pounds we have to divide 10 pounds by 14.4 pounds in a square inch. The answer is .694 inches or slightly more than 1/2 an inch…at sea level on a standard day (standard temp and standard pressure). Now the answer tells you how much area is covered by 10 pounds of air pressure at sea level. Theoretically, this represents 10 pounds of pressure in a cube that begins at the surface of the planet and goes upward until we run out of air…a few miles up at least. So that’s not really answering your question because I don’t know how much “space” we have because I don’t know the altitude we run out of air.
