Condensing film co-efficient for steam on horizontal tubes ranges from
5000 to 15000 Kcal/hr.m2
.°C. Condensation of vapor is carried out inside
the tube in a shell and tube heat exchanger, when the
(A) Higher condensing film co-efficient is desired
(B) Condensate is corrosive in nature
(C) Lower pressure drop through the exchanger is desired
(D) Temperature of the incoming vapor is very high
