Determine the pressure in seawater at a depth of 300 m.

The hydrostatic pressure of water at depth can be calculated using the formula:
Р = ρ * g * h, where Р is the hydrostatic pressure of water (Pa), ρ is the density of salt water (from the table of densities of liquids ρ = 1030 kg / m ^ 3), g is the acceleration of gravity (we take g = 9.8 m / s ^ 2), h – depth (h = 300 m).
Let’s calculate the hydrostatic water pressure:
P = ρ * g * h = 1030 * 9.8 * 300 = 3028200 Pa ≈ 3.03 MPa.
Answer: The pressure of sea water at a depth of 300 m is 3.03 MPa.
