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?
