A vertical vessel with a cylindrical shell and hemispherical heads is to be installed in a closed shed. Internal diameter of the vessel is 1800 mm and its thickness is 12 mm. Tangent to tangent length of the vessel is 10.5 m. the vessel contains a liquid of density 800 kg/m3 . The vessel is filled to 75% of its capacity. Determine the total weight of the vessel and the longitudinal stress in the cylindrical shell above and below the support which is at the lower head to shell junction. Permissible stress of the material is 1040 kg/cm2 . Joint efficiency is 85%. Density of material is 7800 kg/m3
