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 Less than 45°C Initially decreases and remains constant thereafter Equal to 45°C More than 45°C Less than 45°C Initially decreases and remains constant thereafter Equal to 45°C More than 45°C ANSWER DOWNLOAD EXAMIANS APP

Heat Transfer A hollow sphere and a solid sphere of the same material and equal radii are heated to the same temperature. In this case, Both the spheres will emit equal amount of radiation per unit time in the beginning The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant Both B & C Both will absorb equal amount of radiation from the surrounding in the beginning Both the spheres will emit equal amount of radiation per unit time in the beginning The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant Both B & C Both will absorb equal amount of radiation from the surrounding in the beginning ANSWER DOWNLOAD EXAMIANS APP
