Heat Transfer Extended heat transfer surface like fins are used to increase the heat transfer rate. Fin efficiency is defined as the ratio of heat transferred across the fin surface to the theoretical heat transfer across an equal area held at the Constant temperature equal to that of the base Surrounding temperature Average temperature of the fin Temperature of the fin end Constant temperature equal to that of the base Surrounding temperature Average temperature of the fin Temperature of the fin end ANSWER DOWNLOAD EXAMIANS APP
