A diver in a rigid spacesuit can dive to a depth of 250 m, and an experienced diver – to 20 m. Determine the water pressure in the sea at these depths?
Data: h1 (diver’s immersion depth) = 250 m; h2 (immersion depth of an experienced diver) = 20 m; g (acceleration due to gravity) = 9.81 m / s2; ρmv (density of seawater) = 1030 kg / m3.
2.1 Pressure on the diver: Р1 = ρmv * g * h1 = 1030 * 9.81 * 250 = 2526075 Pa ≈ 2.53 MPa.
2.2. Pressure on an experienced diver: P2 = ρmw * g * h2 = 1030 * 9.81 * 20 = 202086 Pa ≈ 202 kPa.
Answer: The pressure for a diver is 2.53 MPa, for an experienced diver – 202 kPa.
