Answer the following questions: Question (1): (10 Marks) A furnace wall is composed of three layers, 10cm of firebrick (k1=1.560W/m.K), followed by 23cm of kaolin insulating brick (k2=0.073W/m.K), and finally 5cm of masonry brick (k3=1.0W/m.K). The temperature of the inner wall surface is T1=1370K and the outer surface is at T4=360K. (a) Calculate the rate of heat loss q for an area A=1m2 of the furnace wall ( 5Marks) (b) What are the temperatures T2 and T3 at the contacting surfaces respectively between the fire brickkaolin and kaolin-masonry brick?
