Steam in a heating system flows through tube whose outer diameter is 10 cm and whose walls are maintained at a temperature of 150°C. Circular aluminum alloy 2024-T6 fins (k = 186 W/m · °C) of outer diameter 15 cm and constant thickness 2 mm are attached to the tube. Heat is transferred to the surrounding air at T∞ = 25°C, with a heat transfer coefficient of 50 W/m2 · °C. If the total tube length is 5 m and spacing between fins is 6 mm then determine: a. The increase in heat transfer rate as a result of adding fins b. Overall effectiveness of the fined surface
