Solving for compression ratio adiabatic

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. WebNov 4, 2016 · Discharge temperatures resulting from high compression ratios can usually be controlled by intercooling. Efficiency • Reciprocating—Reciprocating compressors have a very characteristic adiabatic efficiency curve (Figure 8). As compression ratio drops, adiabatic efficiency drops. Efficiency changes with molecular weight.
