Determine the depth of the diver’s immersion if his porthole operates at a pressure of 200 kPa.

To determine the depth of the diver’s immersion, we use the formula for calculating the hydrostatic pressure:

P = ρ * g * h, where P is the specified hydrostatic pressure on the window (P = 200 kPa = 200 * 10 ^ 3 Pa), ρ is the density of seawater (tabular value ρ = 1030 kg / m3), g is the acceleration of the free fall (const, g = 9.81 m / s2), h – immersion depth.

h = P / (ρ * g).

Let’s perform the calculation:

h = 200 * 10 ^ 3 / (1030 * 9.81) = 19.8 m.

Answer: The depth of the diver’s immersion will be 19.8 meters.
