Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Flows outside the tubes Can flow either inside or outside the tubes Flows through the tube Should not be used as it gives very high pressure drop Flows outside the tubes Can flow either inside or outside the tubes Flows through the tube Should not be used as it gives very high pressure drop ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In a shell and tube heat exchanger, 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 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 ANSWER DOWNLOAD EXAMIANS APP
