Hello, We are an importer of SCUBA diving equipment and are building a pool. I see multiple formulas and opinions, I'm hoping for a KISS answer. Although I don't think Width or length has anything to do with my question, we are building a deep shaft pool that will be 25'Wx35'Lx88'D. What is the force on the walls at 88' please? is it atmospheric pressure, 1 bar per 10m/33' so about 40psi?
