Bondary Discripancy
 

Hi,

I have specified convective boundary condition on the external surface of a t-pipe with h = 2 btu/hr-ft^2-F and T_infinity = 70 F. But after the solution ,the area weighted average of surface heat transfer co-efficient is 0.02 btu/hr-ft^2-F and when Summary--> bondary conditions were printed it prints 11.34 .. Can any body explain this discrpancy...
