Question

Помогите прошу Определите давление на глубине 8,1м в морской воде

Answer 1

P = po * g * h 

po - плотность ( для морской воды 1030 кг / м³ )
g - ускорение свободного падения ( 10 Н / кг )
h - глубина ( 8,1 м )

p = 1030 * 10 * 8,1 = 83430 Па

Answer 2

Determining Pressure at a Depth of 8.1m in Seawater

To calculate the pressure at a depth of 8.1m in seawater, we can use the formula for hydrostatic pressure, which is given by the equation:

P = ρgh

Where: - P = pressure - ρ = density of the fluid - g = acceleration due to gravity - h = depth

Let's calculate the pressure at a depth of 8.1m in seawater using the given formula.

Calculation

Given: - Depth (h) = 8.1m - Density of seawater (ρ) = 1025 kg/m³ (average density of seawater) - Acceleration due to gravity (g) = 9.81 m/s²

Using the formula P = ρgh, we can calculate the pressure at a depth of 8.1m in seawater:

P = (1025 kg/m³) * (9.81 m/s²) * (8.1m)

P ≈ 80829.825 Pascal

So, the pressure at a depth of 8.1m in seawater is approximately 80829.825 Pascal.
