Consider the attic of a home located in a hot climate.The floor of the attic is characterized by a width ofL1?10 m while the roof makes an angle of ??30?from the horizontal direction, as shown in the schematic.The homeowner wishes to reduce the heat load to thehome by adhering bright aluminum foil (?f?0.07) ontothe surfaces of the attic space. Prior to installation of thefoil, the surfaces are of emissivity ?o?0.85.(a) Consider installation on the bottom of the atticroof only. Determine the ratio of the radiation heattransfer after to before the installation of the foil.(b) Determine the ratio of the radiation heat transferafter to before installation if the foil is installedonly on the top of the attic floor.(c) Determine the ratio of the radiation heat transfer if the foil is installed on both the roof bottom andthe floor top
