The fin shown in Figure P13–5 is insulated on the perimeter. The left end has a constant temperature of 100 ° C. A positive heat flux of q* = 1000 W/m² acts on the right end. Let K_xx = 6 W/(m . ° C) and cross-sectional area A = 0.1 m². Determine the temperatures at L/4, L/2, 3L/4, and L, where L = 0:4 m.
