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 W/m K are ka = KE = 26, ke = 11, ko= 26, kp. = 14, and kE = 37. The left and right
surfaces of the wall are maintained at uniform temperatures of 300°C and 100°C,
respectively. Assume heat transfer through the wall to be one-dimensional.
