Calculate the water pressure at the bottom of one of the deepest sea troughs in the Mariana depth which is 10900m and the density of seawater is 1030kg m3

The hydrostatic pressure at the bottom of the Mariana Trench can be calculated using the formula:

Р = ρ * g * h, where ρ is the density of seawater (for salt water ρ = 1030 kg / m3), g is the acceleration of gravity (we assume g = 9.8 m / s2), h is the depth of the Mariana Trench (h = 10900 m).

Let’s calculate the water pressure:

P = ρ * g * h = 1030 * 9.8 * 10900 = 110024600 ≈ 110 MPa.

Answer. The seawater pressure at the bottom of the Mariana Trench is 110 MPa.
