For the square two-dimensional body shown in Figure P13–21, determine the temperature distribution. Let K_xx = K_yy = 25 Btu/(h-ft- ° F) and h = 10 Btu/(h-ft²- ° F). Convection occurs across side 4–5. The free-stream temperature is T_∞ = 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.
