Consider a 5-m-high, 8-m-long, and 0.22-m-thick wall whose representative cross section is as given in the figure. The thermal conductivities of various materials used, in Wim K, are kA- kf

= 2, kg – 8, kc= 20, kp - 15, kE 37. The left and right surfaces of the wall are maintained at uniform temperatures of 300°C and 100°C respectively. Assuming heat transfer through the wall to be one-dimensional, determine the rate of heat transfer through the will in W.
