Heat Transfer Double pipe heat exchangers are used when heat transfer area required is very high because it occupies less floor area when heat transfer area required is very low because it is less costly when heat transfer area required is very high because it occupies less floor area when heat transfer area required is very low because it is less costly 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 There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised ANSWER DOWNLOAD EXAMIANS APP
