7. 8. 9. An experiment is conducted using a fin as shown below. Temperature readings are collected along the length of the fin, which is made from copper with k-400W/m.K. Tb=50C x1 X L = 0.5m x2 h x3 x4 D = 0.05m T=50C (3) Could this be considered a pin fin? Why or why not? Location x (m) 0.00 0.10 0.20 0.30 0.40 (4) Assuming an infinite fin, calculate the heat transfer coefficient in W/m.K. Temperature (K) 323.15 321.29 319.70 318.22 316.84 (3) Assuming a fin with insulated tip, calculate the heat transfer coefficient in W/m2.K. 10. (6) Suppose the same geometry and boundary conditions are used, but the fin is made from aluminum with k=150W/m K. Fill out the temperature readings, assuming insulated tip. Location x (m) 0.00 0.10 0.20 0.30 0.40 Temperature (K) 323.15 11. (2) Calculate fin effectiveness and fin efficiency for the original copper fin with insulated tip. 12. (2) What is the distinction between fin efficiency and effectiveness? Why are these useful?
