1. For the composite wall shown in Figure P13–6, determine
the interface temperatures. What is the heat flux through the 8-cm portion? Use
the finite element method. Use three elements with the nodes shown. 1 cm = 0:01
m.
2. 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.
