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 Finned tube heat exchanger with air inside and steam outside Shell and tube heat exchanger with air on shell side and steam inside tubes Shell and tube heat exchanger with air inside tubes and steam on shell side Finned tube heat exchanger with air outside and steam inside Finned tube heat exchanger with air inside and steam outside Shell and tube heat exchanger with air on shell side and steam inside tubes ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Should not be used as it gives very high pressure drop Flows outside the tubes Can flow either inside or outside the tubes Flows through the tube Should not be used as it gives very high pressure drop Flows outside the tubes Can flow either inside or outside the tubes Flows through the tube ANSWER DOWNLOAD EXAMIANS APP
