VAPOR PRESSURE—PSIA CRITICAL PRESSURE—PSIA

Figure 10-20 Critical pressure ratio for cavitating and flashing liquids other than water. The abscissa is the ratio of the liquid vapor pressure at the valve inlet divided by the thermodynamic critical pressure of the liquid. The ordinate is the corresponding critical pressure ratio, re. (From Fisher Controls, 1987.)
