Heat Transfer 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 Shell and tube heat exchanger with air inside tubes and steam on shell side Finned tube heat exchanger with air outside and steam inside Shell and tube heat exchanger with air on shell side and steam inside tubes Finned tube heat exchanger with air inside and steam outside Shell and tube heat exchanger with air inside tubes and steam on shell side Finned tube heat exchanger with air outside and steam inside Shell and tube heat exchanger with air on shell side and steam inside tubes Finned tube heat exchanger with air inside and steam outside ANSWER DOWNLOAD EXAMIANS APP

Heat Transfer The Sieder-Tate correlation for heat transfer in turbulent flow in pipe gives Nu α Re0.8, where, Nu is the Nusselt number and Re is the Reynolds number for the flow. Assuming that this relation is valid, the heat transfer co-efficient varies with the pipe diameter (D) as (D)1.8 (D)-0.2 (D)-1.8 (D)0.2 (D)1.8 (D)-0.2 (D)-1.8 (D)0.2 ANSWER DOWNLOAD EXAMIANS APP
