For the composite wall idealized by the one-dimensional model shown in Figure P13–7, determine the interface temperatures. For element 1, let K_xx = 5 W/(m . °C); for element 2, K_xx = 10 W/(m . ° C); and for element 3, K_xx = 15 W/(m . °C). The left end has a constant temperature of 200 °C and the right end has a constant temperature of 600 °C.
