Heat Transfer In a shell and tube heat exchanger, There is no relationship between temperature drop and resistance The relationship is not generalised The temperature drops in the two fluids and the wall are proportional to individual resistances The temperature drop is inversely proportional to the resistance across which the drop occurs There is no relationship between temperature drop and resistance The relationship is not generalised The temperature drops in the two fluids and the wall are proportional to individual resistances The temperature drop is inversely proportional to the resistance across which the drop occurs 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 Constant temperature equal to that of the base Temperature of the fin end Surrounding temperature Average temperature of the fin Constant temperature equal to that of the base Temperature of the fin end Surrounding temperature Average temperature of the fin ANSWER DOWNLOAD EXAMIANS APP
