Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Flows outside the tubes Should not be used as it gives very high pressure drop Can flow either inside or outside the tubes Flows through the tube Flows outside the tubes Should not be used as it gives very high pressure drop Can flow either inside or outside the tubes Flows through the tube 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 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 The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance 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 150 125 133 160 150 125 133 160 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Condensing film co-efficient for steam on horizontal tubes ranges from 5000 to 15000 Kcal/hr.m² .°C. Condensation of vapor is carried out inside the tube in a shell and tube heat exchanger, when the Higher condensing film co-efficient is desired Temperature of the incoming vapor is very high Condensate is corrosive in nature Lower pressure drop through the exchanger is desired Higher condensing film co-efficient is desired Temperature of the incoming vapor is very high Condensate is corrosive in nature Lower pressure drop through the exchanger is desired ANSWER DOWNLOAD EXAMIANS APP
