Answer:
P = 84.1 MPa
Explanation:
- The pressure at the bottom of column of of salt water of height h, is given by the following expression:
[tex]P = \rho * g * h (1)[/tex]
where ρ = density of salt water (in Kg/m³),
g = acceleration due to gravity (in m/s²)
h = height of the column of water.
- Replacing by their values in (1):
[tex]P = \rho * g * h = 1023.6kg/m3*9.8m/s2*8380m = 84.1 MPa (2)[/tex]
- Neglecting the atmospheric pressure, the pressure on the cube at the bottom of Puerto Rico Trench is given by (2):
- P = 84.1 MPa.
