Heat is transferred at a rate of 0.1 kW through glass wool insulation (density = 100 kg/m3)
Question:
Heat is transferred at a rate of 0.1 kW through glass wool insulation (density = 100 kg/m3) of 5 cm thickness and 2 m2 area. If the hot surface is at 70?C, determine the temperature of the cooler surface.GIVENGlass wool insulation with a density (ρ) = 100 kg/m3Thickness (L) = 5 cm = 0.05 mArea (A) = 2 m2Temperature of the hot surface (Th) = 70?CRate of heat transfer (qk) = 0.1 kW= 100 WASSUMPTIONSOne dimensional, steady state conductionConstant thermalconductivity
