Question: Collapse depth (or crush depth) is the submerged depth that a submarine cannot exceed without collapsing because of the surrounding water pressure. The collapse depth

Collapse depth (or crush depth) is the submerged depth that a submarine cannot exceed without collapsing because of the surrounding water pressure. The collapse depth of modem submarines is not quite a kilometer (730 m). Assuming seawater to be incompressible (sp. gr. = 1. 03), what is the crush depth pressure in N/m2 and psi (lb/in.2)? Is the pressure you computed absolute or gauge pressure?
