Oms Vs Faber

[LUBOLD8431]

Well, guess what they are the same cylinder. Dont always trust the numbers provided by a manufacturers...

Check out the fine print under OMS and Faber in the following charts ...

As an additional exercise, conduct a search for scuba cylinder specifications and note the discrepency in the same cylinder on various charts.

These are used for comparison purposes only ... not as absolute values.

It's interesting to note that many do not spec the buoyancy characteristics of their cylinders with valves attached ... after all, you can't dive it that way.

Thats all well and nice.. OMS says they use vander walls to calculate delievered volume.. they fail to specify a VERY important fact... What gas are the stating it for? The higher the oxygen content the greater the delievered volume (oxygen is more compressable than nitrogen or helium)

Lets take some immaginary cylinder that has some gas in it thats acting as an ideal gas (its compressibility is 1.00) that has a capacity of 100 (forget about units they dont matter)

now that same cylinder filled with oxygen would be just over 106 units and that same cylinder filled with only nitrogen is just under 97 units
