A brass rod 100 mm long and 5 mm in diameter extends horizontally from a casting at 200oC. The rod is in air with T?=20oC and h=30 W/(m2 K).

a. What is the temperature of the rod at 25, 50, 75, and 100 mm from the casting? Assume that the fin tip is approximately adiabatic.
b. What is the rate of heat transfer from the fin?
c. What would be the rate of heat transfer from a 5 mm diameter circle of the casting surface
without a fin?
