Question
The figure below shows the cross section of a wall made of white pine of
thickness La and brick of thickness La = 2.0La, sandwiching two layers of
unknown material with identical thicknesses and thermal conductivities. The
thermal conductivity of the pine is ka and that of the brick is ka = 5.0ka. The
face area A of the wall is unknown. Thermal conduction through the wall has
reached steady state; the only known interface temperatures are T, = 25 °C,
T, = 20 °C and T; = -10 °C. What is the interface temperature T,?
