Quizplus · Accepted Answer

Fin efficiency is defined as the ratio of the actual heat transferred by the fin to the heat that would be transferred if the entire fin were at the base temperature (which is constant). This comparison helps in understanding how effectively the fin is transferring heat compared to an ideal scenario where the fin's temperature does not decrease along its length.
