Evaluating Heat Transfer

A composite plane wall consists of a 75-mm-thick layer of insulation (ki = 0.05 W/m · K) and a 25-mm-thick layer of siding (k = 0.10 W/m · K). The inner temperature of the insulation is 20°C. The outer temperature of the siding is —13°C. Determine at steady state (a) the temperature at the interface of the two layers, in °C, and (b) the rate of heat transfer through the wall, in W per m2 of surface area.
