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