Spherical vessel formula
WebJan 1, 2024 · The above calculator identifies the internal volume (s) of a vertical pressure vessel with spherical end caps. The vessel comprises five distinct sections; a lower head (V₁,d₁), a lower knuckle (V₂,d₂), a central cylinder (V₃,d₃), an upper knuckle (V₄,d₄) and an upper head (V₅,d₅). The upper and lower heads are identical, as ...

Generally, a pressure vessel is considered to be "thin-walled" if its radius ris larger than 5 times its wall thickness t(r> 5t). When a pressure vessel is subjected to external pressure, the above formulas are still valid.
