Determine the temperature distribution and rate of heat flow per foot length from a 5 cm outer diameter pipe at 180 ° C placed eccentrically within a larger cylinder of insulation (k = 0.058W/ m-° C) as shown in Figure P13–38. The diameter of the outside cylinder is 15 cm, and the surface temperature is 20 ° C.
