a) Compute the fin effectiveness of a bar fin made of Aluminum (k-215 W/m.K) that is 0.18 mm thick and 25 mm long when hr 30 W/m².K, the base temperature is 4 C. and the air temperature is 20 C. b) compute the fin effectiveness if double the thickness of the fin is used. c) compute the fin effectiveness if double the length of the fin is used, d) which one is better (b) or (c) and why? a) Compute the fin effectiveness of a bar fin made of Aluminum (k-215 W/m.K) that is 0.18 mm thick and 25 mm long when hr 30 W/m².K, the base temperature is 4 C. and the air temperature is 20 C. b) compute the fin effectiveness if double the thickness of the fin is used. c) compute the fin effectiveness if double the length of the fin is used, d) which one is better (b) or (c) and why?
