Hello!

In the process of calculating the thickness of a pressure vessel, lets say a very large sphere, we add the static head to the internal design pressure. This value is used to calculate the minimim thickness of the sphere.

How do we account for the dead weight in arriving at the thickness?

Thanks a lot.

The hydrostatic head is

PH(Pa)=Density of the fluid(kg/m³)*Heigth of the fluid column(m)*9,81(m/s²)

Divide the result by 10E5 to arrive at (bar) if you prefer.

The next thing to consider is the weight of the contents and the vessel on the support in the support calculation.

Thank you very much Dr. Koebel,

I saw a beautiful example related to "Thickness Calculation for Internal Pressure Under Supplemental Loadings" in ASME sec VIII Div 1 Appendix L, L-2. Supplemental loadings included are wind and eccentric weights.

Thanks again.
