I understand that, what I am trying to understand is, if you have for instance 1 psi in a 12" cube, is the outward exerted force less than that of a 36" cube with 1 psi? It seems that the larger area would have less force than the smaller area at the same pressurization.
I have a "process" that creates approx. 1.7" of water column throughout a large enclosed surface area, at temperatures ranging from 1500 to 2250 F. I am trying to show the actual force applied to the shell over a large surface area from the known measurment of pressure. For instance, I have 1.7"...
