As mentioned in assumption 1, Boyle's law will not apply if any air from conditions external to the hydrostatic test can reach the air pocket. To me this also means if the pressure were to fall below...

If it is water with a specific gravity of 1 you will lose 0.0361 psi per inch in the container. Example- If the level of the container drops 12 inches you would take 12 x .0361 and you would have a...

Everything depends on the size of the air pocket, since you can treat the water as incompressible. As water is lost, the air pocket expands, lowering the pressure. If the air pocket is large, it takes...
