Homework Help: Submarine's maximum safe depth

  1. Nov 27, 2007 #1
    1. The problem statement, all variables and given/known data

    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.

    2. Relevant equations

    p = p0 + pgd

    3. 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
