Consider an ancient, rigid, but sealed jar resting 80 ft below the surface of the ocean. If the specific gravity of sea water is 1.025 and the barometric pressure is 14.7psia, determine the absolute pressure acting on the jar (in psia).

I already know the answer is 50.3 psi (absolute) I just need some help getting to that point.

DrBob222 · Answer

I gave you a link that is a calculator to do this for you. Are you telling me you can't type in 80 for the depth, hit the units bar and select feet, hit the calculate button and you get a psi in atm but you can hit the units bar again and choose psi. It shows 50.3.Or have I misunderstood what you want?
