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.
