question

A plane wall of an oven consists of an inside layer of refractory brick 6 in. thick (k = 0.08 Btu/hr-ft-°F) followed by a 9 in. layer of common brick (k = 0.8 Btu/hr-ft-°F). If the temperature of the inner wall sur-face is 1800°F and that of the outer surface is 200°F, determine the rate of heat loss per unit area, through this wall.
