A brass rod (k = 133 W/m-K) with a diameter of 5 mm
and a length of 100 mm is used
enhance heat transfer from a surface which is maintained at 200
C. The cylindrical surface of the rod is exposed
to a convection environment with h = 30 W/m2-K and an
ambient temperature of 20
a) Calculate the heat convected away from the
b) Calculate the temperature 50 mm from the
c) Plot the temperature of the rod from the base to
d) Assume you are now allowed to vary the rod length
and you wish to minimize the weight of the rod while
maximizing the heat transfer from the rod. What rod length
would you use?
