Hoop stress and wall thickness in storage tanks

In my ongoing quest to reinvent all the equations in all the engineering codes, I found myself idly wondering why the equations of shell thickness in API 650 are the way they are. You would think that the governing stress in a storage tank is the hoop stress, and the …
