WebMay 24, 2016 · I understand that for air, the critical ratio across an orifice is P/P 0 = 0.53, which corresponds to an x T of 0.47. However, the document linked above (Table 2, page 26) provides some example measurements for valves and shows x T to vary from 0.2 to 0.84 (suggesting critical pressure ratios P/P 0 of 0.8 to 0.14). WebThe critical pressure of a substance can, therefore, be defined as the pressure that must be applied to a substance in order to liquify it at its critical temperature. The critical pressure of a substance is often denoted by the symbol ‘P C ’. The three most common states of matter, namely solid, liquid, and gas, are known to be separated ...
