The diver sank into the sea to a depth of 90 m, determine the pressure at this depth.
| July 7, 2021 | education
To calculate the required pressure of seawater at the considered depth, we will use the formula: P = ρmw * g * h.
Data: ρmw – density of seawater (we will assume ρmw = 1030 kg / m3); g – acceleration of gravity (g = 9.81 m / s2); h is the considered immersion depth (h = 90 m).
Calculation: P = ρmv * g * h = 1030 * 9.81 * 90 ≈ 909.4 * 103 Pa.
Answer: At a depth of 90 m, seawater creates a pressure of 909.4 kPa.
