Max Depth of Submarine Modeling: 80kpa

[HighHoAg]

Hello, I'm working on a project, and my teacher gave me something to think about, but I am at a loss. He wants me to come up with an equation to model the maximum height a submarine can go underwater, if it can withstand a maximum pressure of 80kpa. I started thinking it was an integral problem, integ(dP/dz) but I'm not sure. Any help would be much appreciated.

How does hydrostatic pressure depend on depth? (It's simpler than you think.)

it would be very cool if you solve that with integrals, but its a lot more than you need, really

What they said. No integrals required.

1m head of water = 0.1bar = 10kpa
