13.38 Consider the attic of a home located in a hot climate.
The floor of the attic is characterized by a width of
L₁ = 8 m while the roof makes an angle of 0 = 30° from
the horizontal direction, as shown in the schematic.
The homeowner wishes to reduce the heat load to the
home by adhering bright aluminum foil (ε = 0.07) onto
the surfaces of the attic space. Prior to installation of
the foil, the surfaces are of emissivity & = 0.90.

L₁ = 8 m
(a) Consider installation on the bottom of the attic
roof only. Determine the ratio of the radiation heat
transfer after to before the installation of the foil.
(b) Determine the ratio of the radiation heat transfer
after to before installation if the foil is installed
only 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 and the
floor top.
