Consider a 5.5-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 W/m · °C, are kA= kF= 5.58, kB = 13.18, kC= 29.58, kD= 19.38, and kE = 39.88. 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 wall
