Compare the rate of heat flow from the bottom to the top in the aluminum structure shown in the sketch with the rate of heat flow through a solid slab. The top is at ??10?C, the bottom at 0?C. The holes are filled with insulation which does not conduct heat appreciably.GIVENThe aluminum structure shown in the sketch belowTemperature of the top (TT) = ?? 10?CTemperature of the bottom (TB) = 0?CThe holes are filled with insulation which does not conduct heat appreciablyASSUMPTIONSThe structure is in steady stateHeat transfer through the insulation is negligibleThe thermal conductivity of the aluminum is uniformThe edges of the structure are insulatedTwo dimensional conduction through thestructure
