The wall of a furnace is made up of 9.5 in. firebrick (k=0.72 Btu/hr-ft-'F) 5.3 in. of insulating brick (k=0.08) and 20.30 cm of red brick (k=0.5). The inner and outer surface temperatures tį and t, of the wall are 1500°F and 150°F respectively. Neglecting the resistance of the mortar joints, compute the rate of heat flow through 1 ft? of the wall. 1.
