Spherical pressure vessel stress formula
Web9. gives the following equation for normal stress in a spherical pressure vessel: (9) The stress in a spherical pressure vessel is equal to the longitudinal stress in a cylindrical pressure vessel having the same r/tratio; and it is just half the value of the hoop stress in the cylinder. Thus, for a given pressure, a spherical pressure ves- sel ... WebTheoretically, a sphere would be the best shape of a pressure vessel. Unhappily, a spherical shape is tough to manufacture, therefore more expensive, so most pressure vessels are …
