An offshore oil rig will drill into the ocean floor which is located 1 mile below the water surface. Determine the pressure at that location (i. e. at 1 mile ocean depth). Could a human body withstand that pressure? What would happen to an unprotected, exposed person at that depth? (2360 psi)

    15.65 MPa 150 times of human body internal pressure

    Explanation:

    Given:

    - Depth of the ocean for offshore drilling d = 1 mile

    Find:

    Determine the pressure at that location

    What would happen to an unprotected, exposed person at that depth?

    Solution:

    - The pressure at a certain depth of a fluid can be calculated with:

    P = p_w*g*d

    Where, P is the pressure, p_w is the density of water (997 kg / m^3).

    - Hence @ d = 1.0 mile = 1.6 km = 1600 m:

    P = 997*9.81*1600

    P = 15.65 MPa

    - Whereas the pressure inside a human body is 101 KPa, Pressure under ocean @ 1 mile of depth is 150 times in magnitude, enough to crush the human body!
