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 Irrespective of the shape of the vessel Only if the opening is on a vertical cylinderical vessel Only if the opening is on a horizontal cylinderical vessel Only if the opening is on spherical vessel Irrespective of the shape of the 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 for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes Are less prone to fouling Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less None of these Are easier to clean Are less prone to fouling Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less None of these Are easier to clean ANSWER DOWNLOAD EXAMIANS APP
