An electric kitchen range has a total wall area of 1.40 m2 and is insulted with a layer of fiber glass that has a temperature of 175 oC and its outside surface is 35 oC. The fiber glass has a thermal conductivity of 0.040 Wm-1K-1. Calculate the rate of flow of heat through the insulation, assuming the fibre as a flat slab of area of 1.40 m2.​
