A tube assembly constructed of Cu with an inside diameter of 1.25 cm, wall thickness of 0.8 mm and circumferential fins around the periphery. The fins have thickness of 3 mm, and are spaced 6 mm apart. If the convective heat transfer coefficient from the tube and the fins to the surrounding air is 50 W/m². ⁰C, calculate the thermal resistance for a 30 cm length of the tube fin combination. What is the fin efficiency for this arrangement? If the inside tube temperature is 100 ⁰C and surrounding temperature is 20 ⁰C, what is the heat loss per meter length of the tube? What fraction of heat loss by the fin?
