6. Problem 3 (20 points): A Steam in a heating system flows through tubes whose outer diameter is 3 cm and whose walls are maintained at a temperature of 120°C. Circular aluminum alloy fins (k = 180 W/m.) of outer diameter 6 cm and constant thickness t 2 mm are attached to the tube, as shown in the figure below. The space between the fins is 3 mm, and thus there are 200 fins per meter length of the tube....
