+//================================================================================================================
+clear
+clc
+
+//INPUT
+T=600;//temperature of the equimolar n-butane and n-octane mixture in K
+P=16;//pressure of the equimolar n-butane and n-octane mixture in bar
+Tc=[425.2;569.4];//critical temperature of n-butane and n-octane in K
+Pc=[37.97;24.97];//critical pressure of n-butane and n-octane in bar
+R=8.314;//universal gas constant in J/molK
+
+//CALCULATION
+//For convenience, n-butane is taken as 1 and n-octane as 2
+y1=0.5;//mole fraction of n-butane in the equimolar mixture
+y2=0.5;//mole fraction of n-octane in the equimolar mixture
+Tcm=(y1*Tc(1,:))+(y2*Tc(2,:));//calculation of pseudocritical temperature of mixture using Eq.(9.100) in K
+Pcm=(y1*Pc(1,:))+(y2*Pc(2,:));//calculation of pseudocritical pressure of mixture using Eq.(9.101) in bar
+Trm=T/Tcm;//calculation of pseudoreduced temperature of the mixture using Eq.(9.102) (no unit)
+Prm=P/Pcm;//calculation of pseudoreduced pressure of the mixture using Eq.(9.103) (no unit)
+Zm0=0.9;//value of Zm0 is taken from the generalized compressibility chart, Figure(3.11) corresponding to Trm and Prm (no unit)
+vm=(Zm0*R*T)/(P*10^5);//calculation of the molar volume of the equimolar mixture in m^3/mol
+
+//OUTPUT
+mprintf("\n The molar volume of an equimolar mixture of n-butane and n-octane using the pseudocritical properties estimated through Kays rule = %0.2e m^3/mol\n",vm);
