Determine the water pressure at a depth of 5m.

To determine the pressure in a liquid, we will use Pascal’s law:
The force of pressure inside the liquid at any depth does not depend on the shape of the container where the liquid is located, and the density of the liquid multiplied by the acceleration of gravity and the depth at which the pressure is determined is equal:
P = ρ * g * h, where ρ is the density of the liquid, g is the free fall acceleration of a body raised above the Earth g = 9.8 m / s2, h is the depth of immersion in the liquid.
According to the reference book, the density of water is ρ = 1000 kg / m³.
Substituting numerical values ​​into Pascal’s law, we have:
P = ρ * g * h == 1000 * 9.8 * 5 = 49000 Pa.
Answer: the pressure in the water is 49000 Pa.
