Spherical Pressure Vessel Lets begin by considering a spherical pressure vessel with radius r and wall thickness t subjected to an internal gage pressure p.For reasons of symmetry,all the normal stresses on a small stress element in the wall must be identical.Furthermore,there can be no shear stress.The normal stresses Pressure Vessels Strength of Materials Supplement for Spherical pressure vessels Spherical pressure vessel stress is calculated in the same way as the longitudinal stress.You may conclude that a spherical pressure vessel will require a thinner shell,theoretically one half,than a cylindrical pressure vessel operating at the same pressure and temperature,and therefore it would be a preferred shape.Pressure Vessel,Thin Wall Hoop and Longitudinal Stresses The hoop stress equation for thin shells is also approximately valid for spherical vessels,including plant cells and bacteria in which the internal turgor pressure may reach several atmospheres.Inch-pound-second system (IPS) units for P are pounds-force per square inch (psi).
