A composite wall is shown in Figure P13–8. For element 1, let K_xx = 5 W/(m-° C), for element 2 let K_xx = 10 W/(m-° C), for element 3 let K_xx = 15 W/(m-° C). The left end has a heat source of 600 W applied to it. The right end is held at 10°C. Determine the left end temperature and the interface temperatures and the heat flux through element 3.
