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 Surrounding temperature Constant temperature equal to that of the base Average temperature of the fin Temperature of the fin end Surrounding temperature Constant temperature equal to that of the base Average temperature of the fin Temperature of the fin end ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Double pipe heat exchangers are preferably useful, when Requirement of heat transfer area is low High viscosity liquid is to be cooled A corrosive liquid is to be heated Overall heat transfer co-efficient is very high Requirement of heat transfer area is low High viscosity liquid is to be cooled A corrosive liquid is to be heated Overall heat transfer co-efficient is very high ANSWER DOWNLOAD EXAMIANS APP
