The efficiency of a single cylindrical cross-section fin is 85%. The diameter of the fin is 13 mm and it extends 32 mm from the base. The base is 65 K hotter than the surrounding fluid, and the heat transfer coefficient is 32 W/m2K. How many fins would be required to increase heat transfer from the base by 50 W? Give your answer as an integer.
