A standard oxygen cylinder that contains 244 cf at 2200 psi and 700<span> (6.5 m</span>3<span> at 15200 kPa at 20</span>0C) will contain 122 cf (3.25 m3) when the pressure has dropped to 1100 psi at 700F (7600 kPa<span> at 20</span>0<span>C). In the dissolved acetylene cylinder, the relationship between pressure and remaining acetylene content is less precise.</span>
