The bathyscaphe sank to a depth of 70 m.The water pressure exerted on it is equal to …

To find out the hydrostatic pressure of water on the specified bathyscaphe, we use the formula: Phydr = ρ * g * h.

Const: ρпв – fresh water density (ρпв = 10 ^ 3 kg / m3); ρmv is the density of seawater (ρmv = 1.03 * 10 ^ 3 kg / m3); g – acceleration due to gravity (g ≈ 9.81 m / s2).

Data: h – immersion depth (h = 70 m).

Let’s do the calculation:

– immersion in fresh water: Phydr = ρpw * g * h = 10 ^ 3 * 9.81 * 70 = 686.7 * 10 ^ 3 Pa.

– immersion in seawater: Phydr = ρmw * g * h = 1.03 * 10 ^ 3 * 9.81 * 70 = 707.301 * 10 ^ 3 Pa.

Answer: The hydrostatic pressure of the water on the indicated bathyscaphe is 686.7 kPa (fresh water) or 707.301 kPa (sea water).
