Heat Transfer In case of parallel flow heat exchanger, the lowest temperature theoretically attainable by the hot fluid is __________ the outlet temperature of the cold fluid. Either more or less than (depending upon the fluid) Less than Equal to More than Either more or less than (depending upon the fluid) Less than Equal to More than ANSWER DOWNLOAD EXAMIANS APP
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 133 160 125 150 133 160 125 150 ANSWER DOWNLOAD EXAMIANS APP
