Uniform area, heat transfer problem A stove's walls are made up of a flat inner insulating board 0.01m thick (thermal conductivity: 0.2 W m-1K-1) and a flat outer steel sheet 0.01m thick (thermal conductivity: 26 W m-1K-1). A mineral-wool (thermal conductivity: 0.065 W m-1K-1) is placed between these sheets. The inside temperature of the wall is 773K, how thick does the insulation have to be to maintain the outside wall temperature at 323K ? Assume that the ambient air temperature...
