A cold storage room has a walls constructed of 0.102-m corkboard contained between double wooden walls each 0.0127 m thick. What is the rate of heat loss if wall surface temperature is - 12.2 o C inside and 21.1 o C outside? Also what is the temperature at the interface between the outer wall and the corkboard? Values of kwood = 0.1073 W/mo C and kcorkboard = 0.0415 W/mo C
