Generalized Compressibility Chart

Generalized Compressibility Chart v The p- -T relation for 10 common gases is shown in the Generalized Compressibility Chart . 1 Dr. J. Ortega - Spring 2014 Generalized Compressibility Chart TRpZv In this Chart , the Compressibility factor, Z, is plotted versus the reduced pressure , pR, and reduced temperature TR, where pR = p/pc TR = T/Tc (Eq. ) (Eq. ) (Eq. ) The symbols pc and Tc denote the temperature and pressure at the critical point for the particular gas under consideration. These values are obtained from Tables A-1 and A-1E. kJ/kmol K Btu/lbmol oR 1545 ft lbf/lbmol oR (Eq. ) is the universal gas constant R2 Generalized Compressibility Chart When p, pc, T, Tc, v , and are used in consistent units, Z, pR, and TR are numerical values without units. Example: For air at 200 K, 132 bar, TR = 200 K/133 K = , pR = 132 bar = where Tc and pc for air are from Table A-1.

Generalized Compressibility Chart RT p Z v In this chart, the compressibility factor, Z, is plotted versus the reduced pressure, p R, and reduced temperature T R, where p R = p/p c T R = T/T c (Eq. 3.23) (Eq. 3.27) (Eq. 3.28) The symbols p c and T c denote the temperature and pressure at the critical point for the particular gas under ...
