+// Solution
+
+//From Appendix 3,using the Freon-12 tables, enthalpies are
+h1=28.713; //Unit:Btu/lbm //enthalpy
+h2=28.713; //Unit:Btu/lbm //Throttling gives h1=h2 //enthalpy
+h3=78.335; //Unit:Btu/lbm //enthalpy
+//From the consideration that s3=s4,
+s3=0.16798; //Unit:Btu/(lbm*F) //s=entropy
+//Therefore by interpolation in the superheat tables at 90 F,
+s=0.16798; //entropy at 90F //Btu/lbm*F
+h4=87.192; //Unit:Btu/lbm //enthalpy
