One end of a very long aluminum rod (k= 200 w/m. c) with a diameter of 5 mm is kept at 130 c. if the ambient temperature surrounding the rod, t? is at 30 c and the heat transfer coefficient, h is 120 w/m2 .c. find: a. the temperature distribution in the rod. b. the rate of heat transfer from the rod. c. find what the actual length of the rod must be in order for the infinite length assumption to represent an accurate model d. if instead of aluminum, stainless steel (k= 15 w/m. c) is used would the actual length noted in part c for an accurate infinite length model be higher or lower than what was calculated in part b.
