determine minimum wall thickness of a non-circular pressure vessel
determine minimum wall thickness of a non-circular pressure vessel
(OP)
Have two non-circular vessels that will operate under 10 PSI. Unit is a vibratory feeder, "u"-shaped trough, 18" wide x 132" long. Bolt-on cover is domed in shape. Cover has a inlet opening, trough has a bottom outlet opening. Both openings will be 'sealed' with a molded flexible seal. Been 20+ years since I designed a pressure vessel, need assistance in determining min wall thicknesses of cover and trough. Sketch attached






RE: determine minimum wall thickness of a non-circular pressure vessel
Otherwise, refer to the flat-plate formulas in Roark's Formulas for Stress and Strain, or treat strips of plate as beams. In applying the Roark formulas, you may have to use some that only approximate the actual geometry and boundary conditions, but for small items under low loading, it should suffice.
