One side of refrigerated cold chamber is 6 m long by 3.7 m high and consists of 168 mm thickness of cork between outer and inner walls of wood. The outer wood wall is 30 mm thick and its outside face temperature is 20 deg C, the inner wood wall is 35 mm thick and its inside face temperature is -3 deg C. Taking the coefficient of thermal conductivity of cork and wood as 0.042 and 0.20 W/m-K respectively, calculate the heat transfer per second per sq meter of surface area. Select the correct response: 6.318 J 3.318 J 5.318 J 4.318 J
