Question
a.
presence of a non-condensible 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.
