Consider a 5-m-high and 8-m-wide, and 22-cm-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 = ky = 2, kB = 8, kc = 20, kp1, k-30, and ke-25. The left and right surface surfaces of the wall are maintained at uniform temperature of 300°C and 100°C, respectively. Assuming heat transfer through the wall to be one-dimensional, determine; a) The surface area of the wall, A. b) The individual thermal resistance, R. c) The total resistance, Rtotal- d) The rate of heat transfer through the wall, Q. 300°C 1 cm |C| A 4 cm B 4 cm C 5 cm 6 cm Tecs E 10 cm Ther F 100°C Consider a 5-m-high and 8-m-wide, and 22-cm-thick wall whose representative cross section is as given in the figure.
