At a depth of 3 m in saltwater the pressure is the pressure

At a depth of 3 m in saltwater, the pressure is the pressure at the same depth in fresh water. Greater than, smaller than, the same as

Solution

if the depth remains the same, the pressure is directly propotional to the density.

   p2/p1 = d2/d1

the pressure for the salt water is,

    p2 = (d2/d1)p1

        = [1029 / 1000]p1

        = [1.029]p1

the pressure for salt water is greater than the presure for fresh water.
