A1.3. Steam in a heating system flows through tubes whose outer diameter is 0.05m and whose walls are maintained at a temperature of 180C. Circular aluminum alloy 2024 -T6 fins (k=185W/mC) of outer radius 0.03m and constant thickness 0.001m are attached to the tube. The space between the two fins is 3mm, and thus there are 250 fins per meter length of the tube. Heat is transferred to the surrounding Determine the increase in heat transfer from the tube per meter of its length as a result of adding fins
