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 High heat transfer co-efficient Low pressure drop Less corrosion problems Flexibility possible in the baffle arrangement High heat transfer co-efficient Low pressure drop Less corrosion problems Flexibility possible in the baffle arrangement ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The film co-efficient is decreased due to the presence of non-condensing gases in the vapors. The film co-efficient of superheated vapor as compared to that of saturated vapor is Less Some Either more or less ; depends on the nature of vapor More Less Some Either more or less ; depends on the nature of vapor More ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In a shell and tube heat exchanger, The temperature drops in the two fluids and the wall are proportional to individual resistances The relationship is not generalised There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The temperature drops in the two fluids and the wall are proportional to individual resistances The relationship is not generalised There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs ANSWER DOWNLOAD EXAMIANS APP
