Compressibility Factors: z factor
Tr2.50 Pr0.400 to Tr2.50 Pr5.000
Generalized compressibility factor Z = Z0 + omega*Z1 (Lee-Kesler correlation) as a function of reduced temperature (Tr) and reduced pressure (Pr), plus critical properties (Tc, Pc, acentric factor omega) for ~41 common engineering gases and fluids
