A cross section of a wall made of white pine of thickness La and brick of thickness LI (=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 Kd (=5.0ka). The face area A of the wall is unknown. Thermal conduction through the wall has reached the steady state; the only known interface temperatures are T = 25° C, T2 =20° C and T5=-10° C. What is interface temperature T4? Imagination the cross section and write on it full findings and figures on the drawn typical section from indoor to outdoor case?
