3- A composite wall is shown in Figure. For element 1, let Kx = 5 W (m-°C), for element 2 let Kxx = 10 W (m-°C), for element 3 let Kxx = 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.
