RE: [CAD_CAM_EDM_DRO] OT: Cubic Feet in a Compressed Gas Cylinder?

For my purposes getting everything calculated to point of including Denver's
altitude is not required. I do think that at this altitude it takes less
helium to fill a balloon to a particular size in comparison to sea level,
but unfortunately it take a larger volume of gas to get an equal amount of
lift so you do use more helium in Denver if you want equal lift.
