Could you do a step by step on this question, thanks.

Part B Consider a 5-m-high, 8-m-long, and 0.22-m thick wall whose representative cross section is as given in Fig. 4. The thermal conductivities of various materials used, in W/mK, are ks = kg = 2, kg = 8, ko =20, kp = 15 and kg = 35. 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 (ithe rate of heat transfer through the wall; (ii) the temperature at the point where the sections B, D and E meet; and (ii) the temperature drop across the section F. Disregard any contact resistances at the interfaces. 100C 300C ^ C A 4 cm D 6 cm F B 4 cm E Tc 6 cm 4 cm 8 m 1 cm 5 cm 10 cm 6 cm
