In a gas-liquid shell and tube heat exchanger, the
(A) Presence of a non-condensable gas decreases the condensing film coefficient
(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', 'b' & 'c'
