WebNov 16, 2007 · If you simply compress the air adiabatically, at say, a compression ratio of 30-1, and then inject water to cool it, one gets different answers than if you compress the air to a given temperature (600K for ease of calcuation -- roughly 300 C, which is comfortably less than the temperature at which steel loses strength) and then isothermally compress … WebBottom line: whether the compression makes more liquid or more gas depends not just on p and T but also on the starting liquid/gas ratio. There's a special liquid/gas ratio at each T, and whichever phase beats that ratio gains further, compared to the special ratio, as the cylinder is compressed. It's sort of like economics.
