+
+//INPUT
+T=100;//temperature of carbon dioxide in degree celsius
+P=10;//pressure of carbon dioxide in MPa
+B0=104.76*10^-6;//Beattie-Bridgman constant for carbon dioxide in m^3/mol
+b=72.35*10^-6;//Beattie-Bridgman constant for carbon dioxide in m^3/mol
+C=660.0;//Beattie-Bridgman constant for carbon dioxide in (m^3 K^3)/mol
+R=8.314;//universal gas constant in J/molK
+v=0.233*10^-3;//volume calculated in Example (8.3) in m^3/mol
+Z=0.751;//compressibility factor as calculated in Example (8.3) (no unit)
+
+//CALCULATION
+T=T+273.15;//conversion of temperature in K
+//calculation of entropy departure using Eq.(8.38) in J/molK
+dep_s=(R*log (Z))-(((B0*R)+((2*C*R)/(T^3)))*(1/v))+(((b*B0*R)-((2*C*B0*R)/(T^3)))*(1/(2*(v^2))))+((2*b*C*B0*R)/(3*(T^3)*(v^3)));
+
+//OUTPUT
+mprintf("\n The entropy departure for carbon dioxide using the Beattie-Bridgman equation of state = %f J/mol K\n",dep_s);

+//DISCLAIMER: THE PROBLEM STATEMENT MENTIONS THE TEMPERATURE TO BE 100 DEGREE CELSIUS, WHICH CORRESPONDS TO A TEMPERATURE OF     373.15K. HOWEVER, THE AUTHOR HAS EVALUATED THE ENTROPY DEPARTURE FOR A TEMPERATURE OF 313.15K, WHICH IS CLEARLY A PRINTING ERROR. THE CODE ABOVE HAS BEEN WRITTEN FOR THE TEMPERATURE OF 373.15K  AS GIVEN IN THE PROBLEM STATEMENT.
