If a person is considered a material point, then the excess pressure p, Pa, acting on him at a depth of h, m, from the side of water with a density of ρ, kg / m³, is
p = ρ * g * h,
where g = 9.81 m / s² is the acceleration of gravity at the Earth’s surface.
Then
p = 1030 * 9.81 * 2 ≈ 20209 Pa ≈ 20.2 kPa.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
