baffle design in a rectangular tank 1

[mechatronic]

We have rectangular tank made of A516. The whole weight of the tank will act on a centre baffle plate which supports the tank. The baffle plate devides the whole tank.

Additionally either at one half of the tank the liquid sulphur is filled. Can any one guide me how to decide the baffle plate thickness

I understand to calculate the tanks weight acts on baffle. but how to arrive at horizontal load due to liquid sulphur acting on the plate and arrive at thickness

please help - thanks in advance

That sounds like a very unusual tank, in uncommon service.

Can you get some local help with it?

Refer to the flat plate formulas in Roark's Formulas For Stress and Strain for starters.

Having a flat divider in a tank is a major structural problem if the tank is of any size- don't be surprised if your results are unreasonable.

You might also want to check ship design codes, since a flooded compartment is a close approximation to your loading condition, if not the extra-exciting fluid you are involved with.

You could do some sensitivity studies via FEA with plate elements, compare that to some Roark hand calcs for flat plates, then do final design FEA and check calcs to see if you missed anything.

What size is the tank? If it is small, a mockup could help with deflections and connections (and fabrication issues).

You plate thickness could also be influenced by weld size requirements.....
