Atmospheric pressure vessel design
Thread Content
How is the pressure on the side walls of the shell calculated during the design of a pressure vessel at atmospheric pressure? :loveliness:
JB4735; there’s another reference book, but I’ve forgotten its name.
I’m learning *4735, but it’s not there!
No calculation is needed; analog design will suffice.
I think for pressure vessels at normal pressure, especially those that are square in shape, the values are generally determined based on experience.
Calculate the wall thickness based on the hydrostatic pressure per JB4735-97, and then add an additional amount to the wall thickness.
But isn’t the hydrostatic pressure of the liquid column only applied to the bottom end?
If it is a flat base that sits directly on the ground, the liquid column has no effect on the bottom plate at all, as its effect is counteracted by the ground. Of course, if it is supported by brackets, then that factor needs to be taken into consideration. However, it also has an impact on the side walls; as the liquid column deepens, the greater the force exerted on the side walls.
