Sosp.info How are spherical tanks supported by vertical legs?Such spheres are normally supported upon vertical legs attached to the vessel at its equator. In order to withstand the compressive stresses the total cross sectional area of the lags must increase linearly with the weight of the vessel. The volume of spherical vessel is proportional to the third power of the vessel diameter.See all results for this questionsp.info How are spheres supported in a storage tank?Such spheres are normally supported upon vertical legs attached to the vessel at its equator.
