External Pressure on Vessel
External Pressure on Vessel
(OP)
Hi.. Im currently using pv elite as the software aproved by the client, but im getting an error, induced by external pressure. I would like to know if it is mandatory to run an external pressure design on the vessel, using 14.7 psi as the external pressure, the issue its that im obtaning a shell thickness too high. Its there any criteria to input the external pressure in the design process. Do I have to use 14.7 psi or just 0 psi.
Thanks
Thanks

I've seen it commonly done to design for "Full Vacuum" = (14.7 psi)if a vacuum condition might exist. If you want to design for a lesser vacuum, you must determine the worst case vacuum that might be generated. If you can do that, then it would be alright to design for that less severe condition.
