+
+//INPUT
+T1=100;//temperature of water in degree celsius
+del_hv1=2256.94;//enthalpy of vaporization at T1 in kJ/kg
+T2=150;//temperature at which the enthalpy of vaporization is to be determined in degree celsius
+Cp_f=4.26;//isobaric heat capacity of liquid in kJ/kgK
+Cp_g=1.388;//isobaric heat capacity of vapour in kJ/kgK
+
+//CALCULATION
+del_hv2=((Cp_g-Cp_f)*(T2-T1))+del_hv1;//calculation of the enthalpy of vaporization at T2 using Eq.(7.98) (Kirchhoff equation) in kJ/kg
+
+//OUTPUT
+mprintf("\n The enthalpy of vaporization at 150 degree celsius=%0.2f kJ/kg\n",del_hv2);
