Think on it a bit closer: -- The expansion is happening in the high-pressure reservoir, as some of the air leaves and the rest expands to fill the volume. So you'd expect the supply tank to cool as it empties. -- The compression is happening in the SCUBA tank, where you're continuously stuffing more and more air into the same volume. So you expect the SCUBA tank to warm as it fills.
The numbers on a scuba tank reveal 3 things. Serial no. of the tank. Type metal. and the current hydro date.
There were two hours and forty minutes between the crash and the sinking.
Yes the main difference is a SCUBA tank is used for high pressure breathing air (3200-5000 PSI). A paintball tank has a lower PSI rating and is also measured in ounces not PSI. Even though most people use a breathing air compressor to fill paintball tanks.
