Exercise 5 the bobul 3-75 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 k, = kp=2, kg = 8, ke=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 (a) the rate of heat transfer through the wall; (b) the temperature at the point where the sections B, D, and E meet; and (c) the temperature drop across the section F. Disregard any contact resistances at the interfaces. Re 300°C Ri A A cof 4 cip 5 cm اللي نفس اللوك يسني نفى المتريال D 100 10 cm 6 cm 100°C 12CM 8.12
