chemical engineering heat transfer
1. 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
(A): equal to 45°C
(B): initially decreases and remains constant thereafter.
(C): less than 45°C
(D): more than 45°C
