Question: 115 cnm in a steambased heating system the outside surface...

Question details

11.5 cnm In a steam-based heating system, the outside surface of a finned pipe of (ri-1.5 cm) is maintained at a constant temperature of 120 °C using either circular fins or straight rectangular fins. The fin assembly will be cast from aluminum (k 180 W/mK, p -2700 kg/m3) and the space allocated for this assembly is limited to 1 m in length and 6 cm in diameter. The overall system is exposed to the surrounding air at, T 25°C with a combined heat transfer coefficient of h-60 W/m2 °C 1- Investigate and discuss the effect of fin thickness and fin spacing, and the fin length on the total heat dissipation rate and weight of the assembly.
