For the square two-dimensional body shown in Figure P13–21,
determine the temperature distribution. Let K

=
25 Btu/(h-ft-F) and h = 10 Btu/(h-ft
2
– F). Convection occurs across
side 4–5. The free-stream temperature is Ty = 50 F. The temperatures at nodes 1
and 2 are 100 F. The dimensions of the body are shown in the figure. Take the
thickness of the body to be 1 ft.
