A thin brass pipe, 3 cm in outside diameter, carries hot water at 85 It is proposed to place 0.8 mm thick straight circular fins on the pipe to cool it. The fins are 8 cm in diameter and are spaced 2 cm apart. It is determined that h will equal 20 W/m²°C on the pipe and 15 W/m²°C on the fins, when they have been added. If T = 22°C, compute the heat loss per meter of pipe before and after the fins are added.
