+// Solution
+
+//From the saturation table at 1 psia,
+hf=69.74; //Btu/lbm //saturated liquid enthalpy
+hfg=1036.0; //Btu/lbm //Evap. Enthalpy
+hg=1105.8; //Btu/lbm //The enthalpy of saturated steam
+x=0.97; //Quality
+//Because the condensation process is carried out at constant pressure,the energy equation is q=deltah.
+hx=hf+(x*hfg); //the initial enthalpy //Btu/lbm
+printf("The initial enthalpy is %f Btu/lbm\n",hx);
+//The final enthalpy is hf=69.74.So,
+deltah=hx-hf; //The enthalpy difference //Btu/lbm
+printf("At 1 psia,The enthalpy difference is %f Btu/lbm\n",deltah);
+printf("By the computer solution,the enthalpy difference is 1004.6 Btu/lbm");
