Heat Transfer Extremely large or small volumes of fluids are generally best routed through the shell side of a shell and tube heat exchanger, because of the Flexibility possible in the baffle arrangement Low pressure drop High heat transfer co-efficient Less corrosion problems Flexibility possible in the baffle arrangement Low pressure drop High heat transfer co-efficient Less corrosion problems ANSWER DOWNLOAD EXAMIANS APP
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 Temperature of the fin end Average temperature of the fin Constant temperature equal to that of the base Surrounding temperature Temperature of the fin end Average temperature of the fin Constant temperature equal to that of the base ANSWER DOWNLOAD EXAMIANS APP
