Need Help in Fuel Storage Tank Design

Too much liability to do your design work for you.

Try this:

TANK - API 650/653 Oil Storage Tank design

I don't know if it will help.

Calculate the height required to provide the required volume, i.e. h = Volume/Area. Pressure of liquid at any point is depth times density.

I hope it is for water storage, if your space is that critical.

If the tank were filled with water.... 1 foot of head (height of water) = 2.31 psi Therefore a 10' high tank would exert 231 psi @ the bottom, exactly half that pressure @ 5' and 0 psi at the top of the tank. REGARDLESS OF THE TANK DIAMETER. nuff said

You are mixed up and completely wrong.

The rule is that 2.31 ft of water equals 1 psig

A ten foot tall tank full of water would exert about 4.3 psig at the bottom not 231 psig.

When I was much younger, I used to swim in a flooded quarry in NH. I could free dive down about 15-20 feet. With your numbers, I should have been crushed at that depth.

Your comments about diameter is accurate, though.
