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 a horizontal cylinderical vessel Only if the opening is on spherical vessel Only if the opening is on a vertical cylinderical vessel Irrespective of the shape of the vessel Only if the opening is on a horizontal cylinderical vessel Only if the opening is on spherical vessel Only if the opening is on a vertical cylinderical vessel Irrespective of the shape of the vessel ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design When one of the fluids is highly corrosive and has fouling tendency, it should Perferably flow outside the tube Preferably flow inside the tube for its easier internal cleaning Flow at a very slow velocity Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current Perferably flow outside the tube Preferably flow inside the tube for its easier internal cleaning Flow at a very slow velocity Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design High pressure fluid in a shell and tube heat exchanger should preferably be routed through the Shell side, if the flow is counter-current and tube side if the flow is co-current Tubes to avoid the expansion of high pressure shell construction Shell side for smaller total pressure drop Shell side for large overall heat transfer co-efficient Shell side, if the flow is counter-current and tube side if the flow is co-current Tubes to avoid the expansion of high pressure shell construction Shell side for smaller total pressure drop Shell side for large overall heat transfer co-efficient ANSWER DOWNLOAD EXAMIANS APP
