Air is to be heated by condensing steam. Two heat exchangers are
available (i) a shell and tube heat exchanger and (ii) a finned tube heat
exchanger. Tube side heat transfer area are equal in both the cases. The
recommended arrangement is
(A) Finned tube heat exchanger with air inside and steam outside
(B) Finned tube heat exchanger with air outside and steam inside
(C) Shell and tube heat exchanger with air inside tubes and steam on shell
side
(D) Shell and tube heat exchanger with air on shell side and steam inside
tubes
