Process Equipment and Plant Design A claming section before the liquid flows into the downcomer is privided to Ensure better vapour-liquid contact Reduce the discharge fluctuation Permit release of entrained vapour in the liquid Cool the liquid before it flows down Ensure better vapour-liquid contact Reduce the discharge fluctuation Permit release of entrained vapour in the liquid Cool the liquid before it flows down ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design A certain pressure vessel manufacturer avoids doing reinforcements calculations for openings by always providing a reinforcing pad extending upto double the diameter of the opening and of the same material and thickness as that of the shell wall. If area compensation is accepted as a code guideline, his approach leads to safe design Only if the opening is on spherical vessel Irrespective of the shape of the vessel Only if the opening is on a horizontal cylinderical vessel Only if the opening is on a vertical cylinderical vessel Only if the opening is on spherical vessel Irrespective of the shape of the vessel Only if the opening is on a horizontal cylinderical vessel Only if the opening is on a vertical cylinderical vessel ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Can accomodate less number of tubes for a given shell diameter Results in higher shell side pressure drop Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Results in higher shell side pressure drop Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient ANSWER DOWNLOAD EXAMIANS APP
