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 125 160 150 133 125 160 150 133 ANSWER DOWNLOAD EXAMIANS APP

Heat Transfer In a heat exchanger with steam outside the tubes, a liquid gets heated to 45°C, when its flow velocity in the tubes is 2 m/s. If the flow velocity is reduced to 1 m/s, other things remaining the same, the temperature of the exit liquid will be Initially decreases and remains constant thereafter More than 45°C Less than 45°C Equal to 45°C Initially decreases and remains constant thereafter More than 45°C Less than 45°C Equal to 45°C ANSWER DOWNLOAD EXAMIANS APP
