A submarine dives down to a depth 9.5 beneath the surface of the ocean. Calculate the pressure in atmospheres at that depth, assuming the density of water is 1029 kg/m3, and the air pressure at the surface is 101.5 kPa

  1. Damon

    101.5 * 10*3 + 1029 *9.81 * 9.5
    = 101.5 * 10^3 + 95.898 * 10^3
    = 197 k Pa

    or about 2 atmospheres

    note, 30 feet deep is about additional atmosphere
