Consider the composite wall shown in Fig. 2.23. The concrete and brick sections are of equal thickness. Determine T1, T2, q, and the percentage of q that flows through the brick. To do this, approximate the heat flow as one-dimensional. Draw the thermal circuit for the wall and identify all four resistances before you begin. Neglect heat flow through the interface between the brick and the concrete. Was it valid to treat the problem as one dimensional? [47.6% through brick]
