Question details

Circular fins with a rectangular cross-section were mounted on a tube with the external de 30 mm and internal d 25 mm diameters. The tube is L 1.2 m long and is made from a material with thermal conductivity λ=150W/(m-K). The fins have a height of h-45 mm and thickness δ =4 mm. The internal and the external convective heat transfer coefficients and are = 8 W/(m2·K) α-= 850 W/(m-K), respectively. How many times can the heat stream from the tube to the surrounding air be increased if the minimum distance between fins is s 12 mm? Neglect heat lost by tip of the fins
