+// 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

+percentoferror=(h-271.46)/271.46;

+printf("Percent of error is %f\n",percentoferror*100);
