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 Irrespective of the shape of the vessel Only if the opening is on a vertical cylinderical vessel Only if the opening is on spherical vessel Only if the opening is on a horizontal cylinderical vessel Irrespective of the shape of the vessel Only if the opening is on a vertical cylinderical 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 Heat transfer co-efficient, hG(Kcal/hr.m² .°C) and mass velocity of air, G (kg/hr.m² ) for air flow parallel to the surface in case of constant drying rate in batch drying is related as hG = 0.0176G0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to HG = 0.0176G0.37 0.0176G1.37 1.004G0.8 HG = 1.004G0.37 HG = 0.0176G0.37 0.0176G1.37 1.004G0.8 HG = 1.004G0.37 ANSWER DOWNLOAD EXAMIANS APP
