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 vertical cylinderical vessel Irrespective of the shape of the vessel Only if the opening is on spherical vessel Only if the opening is on a horizontal cylinderical vessel Only if the opening is on a vertical cylinderical vessel Irrespective of the shape of the vessel Only if the opening is on spherical vessel Only if the opening is on a horizontal cylinderical vessel ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Smoker's equation for the calculation of number of equilibrium stages in a continuous binary distillation column is used, when the Number of equilibrium stages in only stripping section is to be calculated Feed is not at its bubble point Relative volatility is close to one (e.g., separation of close boiling isomers) Number of equilibrium stages required is likely to be very small Number of equilibrium stages in only stripping section is to be calculated Feed is not at its bubble point Relative volatility is close to one (e.g., separation of close boiling isomers) Number of equilibrium stages required is likely to be very small ANSWER DOWNLOAD EXAMIANS APP
