Circular fins made of fixed rectangular aluminum (k = 200 W / mK) with a thickness of t = 0.5 mm along L = 15 mm, with 250 pieces of 1 meter pipe length, are well fixed on the pipe with an outer radius of 10 mm. Find the increase in heat transfer of finned tube with respect to bare tube. Heat convection coefficient is 50 W / m2K in bare pipes and 40 W / m2K in finned pipes.
