A person can descend to a depth of 9 m, calculate the water pressure on a person at this depth.

Initial data: h (maximum depth to which a person can dive) = 9 m.

Reference data: g (acceleration of gravity) = 10 m / s ^ 2; by the condition ρ (density of salt water) = 1030 kg / m ^ 3.

The hydrostatic pressure of salt water per person is determined by the formula: P = ρ * g * h.

Let’s calculate: P = 1030 * 10 * 9 = 92,700 Pa or 92.7 kPa.

Answer: The pressure of salt water per person is 92.7 kPa.
