Steam in a heating system flows through tubes whose outer diameter is 5cm and whose walls are maintained at a temperature of 180C. Circular aluminum alloy 2024T6 fins (k=186W/mK) of outer diameter 6cm and constant thickness 1mm are attached to the tube. The space between the fins is 3mm, and thus there are 250 fins per meter length of the tube. Heat is transferred to the surrounding air at T=25C, with a heat transfer coefficient of 40W/m2K. Determine the increase in heat transfer from the tube per meter of its length as a result of adding fins
