The fin efficiency is defined as the ratio of the actual heat transfer from the fin to the heat transfer from the same fin if the temperature along the entire length of the fin is the same as the base temperature.
Definition of Fin Efficiency
The fin efficiency is an important parameter in heat transfer analysis of fins. It is defined as the ratio of the actual heat transfer from the fin to the heat transfer from the same fin if the temperature along the entire length of the fin is the same as the base temperature.
Explanation
To understand why the correct answer is option 'C', let's consider the different options one by one:
- Option 'A': the heat transfer from the same fin with an adiabatic tip
An adiabatic tip means that there is no heat transfer from the tip of the fin. However, in reality, heat transfer occurs from the entire length of the fin, including the tip. Therefore, option 'A' is not the correct choice.
- Option 'B': the heat transfer from an equivalent fin which is infinitely long
An infinitely long fin is a theoretical concept used for simplifying calculations. It assumes that the temperature along the entire length of the fin is the same as the base temperature. However, in practical cases, the temperature distribution along the fin length is not uniform. Therefore, option 'B' is also not the correct choice.
- Option 'C': the heat transfer from the same fin if the temperature along the entire length of the fin is the same as the base temperature
Option 'C' is the correct choice because it considers the actual temperature distribution along the fin length. In most practical cases, the temperature at the fin base is higher than the temperature at the fin tip. Therefore, by comparing the actual heat transfer from the fin to the heat transfer from the same fin with uniform temperature distribution, we can determine the fin efficiency.
- Option 'D': the heat transfer from the base area of the same fin
Option 'D' is not the correct choice because it only considers the heat transfer from the base area of the fin, neglecting the heat transfer from the fin surface. The fin efficiency takes into account the entire length of the fin for calculating the heat transfer.
Conclusion
In conclusion, the fin efficiency is defined as the ratio of the actual heat transfer from the fin to the heat transfer from the same fin if the temperature along the entire length of the fin is the same as the base temperature. This definition considers the actual temperature distribution along the fin length and is the most accurate representation of the fin's heat transfer performance.
