Heat Transfer In a shell and tube heat exchanger, The relationship is not generalised The temperature drop is inversely proportional to the resistance across which the drop occurs There is no relationship between temperature drop and resistance The temperature drops in the two fluids and the wall are proportional to individual resistances The relationship is not generalised The temperature drop is inversely proportional to the resistance across which the drop occurs There is no relationship between temperature drop and resistance The temperature drops in the two fluids and the wall are proportional to individual resistances ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer For the same heat load and mass flow rate in the tube side of a shell and tube heat exchanger, one may use multipass on the tube side, because it Decreases the pressure drop Increases the overall heat transfer coefficient Decreases the outlet temperature of cooling medium None of these Decreases the pressure drop Increases the overall heat transfer coefficient Decreases the outlet temperature of cooling medium None of these ANSWER DOWNLOAD EXAMIANS APP
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
