+// Problem 5.16 (page no. 202)
+// Solution
+
+//It is necessary to ontain the saturation values corresponding to 300 F.This is done by reading Table A.1 in Appendix 3,which gives
+pf=66.98; //psia //pressure
+vf=0.017448; //ft^3/lbm //specific volume
+hf=269.73; //Btu/lbm //enthaply
+//Now,
+p=1000; //psia //pressure
+J=778; //Conversion factor //ft*lbf/Btu
+//From eq.5.5,
+h=hf+((p-pf)*vf*144)/J; //1ft^2=144 in^2 //The enthalpy of subcooled water //Btu/lbm
+printf("The enthalpy of subcooled water is %f Btu/lbm\n",h);
+//The difference between this value and the value found in problem 5.15,expressed as a percentage is
