All things being equal, for dynamic loaded beams, which is stronger-larger section modulus- steel I beam or seel C section, as it applies to steel frames on over the road heavy duty trailers.
I am looking for help in determining the head space in an eliptical pertoleum tank as follows
128" long
head size width 89.5
head size height 61"
tank capacity is 2600 usg.
I need to have a minimum of 250 liters of head space to prevent from overloading.
How do I calculate the volume
Thanks
