8. The wall of a cold storage room is composed of brick, concrete and cork insulation with thickness of 4 in, 3.5 in, and 5 in, respectively. The air temperature inside the room is maintained at -16°C while the exterior surface (i.e. brick) is at 18°C. Thermal conductivity for brick, concrete and cork is 0.69, 0.76 and 0.043 J/m-s-°C, respectively. Calculate the rate of heat transfer for each square meter of wall area, and the temperature at the brick-concrete and concrete-cork interfaces. AT; AT AT,
