Steam in a heating system flows through tubes whoseouter diameter is 3 cm and whose walls are maintained at a temperature of 120T. Circular aluminum alloy fins (k = 180 W/m∙K) of outer diameter 6 cm and constant thickness t = 2 mm are attached to the tube, as shown in Fig. P17−i22. The space between the fins is 3 mm, and thus there are 200 fins per meter length of the tube. Heat is transferred to the surrounding air at 25°C, with a combined heat transfer coefficient of60 W/m2∙K. Determine the increase in heat transfer from the tube per meter of its length as a result of adding fins.
