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
Equal to 45°C
Less than 45°C
Initially decreases and remains constant thereafter
Gases to be heated/cooled is normally routed through the shell side, because the corrosion caused by the cooling water or steam condensate remain localised to the tubes
Presence of a non-condensible gas decreases the condensing film co-efficient
All of these
Gases under high pressure are routed through the tube side, because high pressure gases are corrosive in nature
