    A submarine is at a depth of 90m below the surface of the sea. Pressure of the atmosphere is 1.03 * 10^5 Pa

    What is the absolute pressure at this depth? Density of sea water is 1019kg/m^3

    What is the force on a latch of the submarine of dimensions 3m * 4m at this depth?

    Solution Preview

    Let P_A = 1.03x10^5 Pa be the atmospheric pressure,
    d = 1019kg/m^3 be the density of sea water,
    h = 90m be the depth
    g = 9.8 m/s^2 be the free fall acceleration

    The absolute pressure at this depth is

    P = P_A + dgh = 1.03x10^5 Pa + 1019kg/m^3 * 9.8 m/s^2 * 90m ...

    Solution Summary

    The absolute pressure at depths of water in the sea is determined. The force on a latch of the submarine of dimensions 3m * 4m at this depth is found.
