The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines, where the depth of the bottom of the trench is about 11.0 km. Calculate the pressure due to the ocean at a depth of 9.2 km, assuming sea water density is constant all the way down. (The validity of the assumption of constant density is examined in one of the integrated concept problems.

Answer:

The value is [tex]P = 892.7 \ atm[/tex]

Explanation:

From the question we are told that

   The depth of the bottom of the trench is  [tex]d = 11.0 \ km =11000 \ m[/tex]

    The depth considered is  [tex]h = 9.2 \ km = 9200 \ m[/tex]

Generally the pressure is mathematically represented as

         [tex]P = \rho * g * h[/tex]

Here [tex]\rho[/tex] is the density of water with value [tex]\rho = 1000 \ kg/m^3[/tex]

=>      [tex]P = 1000 * 9.8 * 9200[/tex]

=>      [tex]P = 9.016*10^{7} \ Pa[/tex]

Converting to  atmosphere

=>       [tex]P = \frac{9.016*10^{7} }{101*10^{3}}[/tex]

=>       [tex]P = 892.7 \ atm[/tex]
