Q. In a gas-liquid shell and tube heat exchanger, the (Solved)
1. Presence of a non-condensable gas decreases the condensing film co-efficient
2. Gases under high pressure are routed through the tube side, because high pressure gases are corrosive in nature
3. 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
