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
