In a gas-liquid shell and tube heat exchanger, the_________________?
(A) Presence of a non-condensable gas decreases the condensing film co-efficient
(B) Gases under high pressure are routed through the tube side, because high pressure gases are corrosive in nature
(C) 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
(D) All A,
