Heat Transfer A composite flat wall of a furnace is made of two materials 'A' and 'B'. The thermal conductivity of 'A' is twice of that of material 'B', while the thickness of layer of 'A' is half that of B. If the temperature at the two sides of the wall are 400 and 1200°K, then the temperature drop (in °K) across the layer of material 'A' is 160 133 125 150 160 133 125 150 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient 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 Flows outside the tubes Can flow either inside or outside the tubes ANSWER DOWNLOAD EXAMIANS APP
