3. A pin fin is constructed as shown in the figure below of pure copper (look up value of copper).Determine the (a) fin efficiency, (b) fin resistance, (c) fin effectiveness, and (d) heat rate of the fin assuming adiabatic tip. Use table 3.5 from the book. Convert the fin into a straight rectangular fin with the same surface area and diameter (t=D) and length (L=L) as the pin fin.Repeat calculations and compare answers. Which fin design is most effective?
