What is the submarine's maximum safe depth?

[aligass2004]

Homework Statement

A research submarine has a 17cm diameter window 6.0 cm thick. The manufacturer says the window can withstand forces up to 1.0X10^6 N. What is the submarine's maximum safe depth? Assume that the pressure inside the submarine is maintained at 1.0atm and that the density of seawater is 1030 kg/m^3.

Homework Equations

p = p0 + pgd

The Attempt at a Solution

I tried the following

1.0X10^6 = 1.013X10^5 + (1030)(9.8)d, and I got d = 89.033 and of course it was wrong.

What's the relationship between force and pressure ?

p = F/A
