Chemical Heat Transfer

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, B. & C.

A. Gives a higher shell side pressure drop
B. Gives a lower shell side pressure drop
C. Can pack more surface area into a shell of given diameter
D. None of these

A. Black
B. White
C. Coloured
D. All A., B. & C.

A. Condense the steam flowing in the pipeline
B. Remove water resulting from partial condensation of steam
C. Stop the supply of steam
D. None of these

A. Cold fluid is heated to a certain temperature by condensing steam (isothermal fluid)
B. Outlet temperature of both the hot and cold fluid are same
C. Outlet temperature of hot fluid is less than the outlet temperature of the cold fluid
D. None of these

A. Remove non-condensable gases
B. Purge the condenser
C. Facilitate easy cleaning of tubes
D. None of these

A. Lower tube side pressure drop
B. Lower shell side pressure drop
C. Higher tube side heat transfer co-efficient
D. Higher shell side heat transfer co-efficient

A. Von-Karman
B. Reynolds
