Section 1.2: Steady-State 1-D Conduction without Generation 1.2-1 A plane wall is a composite of a low conductivity material (with thickness L 1 and conductivity k 1 ) and a high conductivity material (with thickness L 2 = L 1 and conductivity k 2 ). The edge of the wall at x = 0 is at temperature T 1 and the edge at x = L 1 + L 2 has temperature T 2 , as shown in Figure P1.2-1(a). T 1 is greater than T 2 . The wall is at steady-state and the temperature distribution in the wall is one-dimensional in

Sketch the heat flux ( q ) and temperature ( T ) as a function of position within the wall on the axes in Fig. 1.2-1(b). Make sure that your sketch reflects the fact that (1) the wall is at steady state, and (2) k 1 < k 2....
