Consider the composite wall shown in Fig. The concrete and brick sections are of equal thickness. Determine T1, T2 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.
