The density of kerosene is 800 kg / m3, and the pressure is 40,000 Pa, find the depth (h)

According to Pascal’s law:
The hydrostatic pressure inside the liquid at any depth does not depend on the shape of the vessel in which the liquid is located, and is equal to the product of the density of the liquid, the acceleration of gravity and the depth at which the pressure is determined:
P = ρ * g * h, where ρ is the density of the liquid, g is the acceleration of gravity of a body raised above the Earth g = 9.8 m / s2, h is the depth of immersion in the liquid.
Let us express from this formula the depth of immersion:
h = P / (ρ * g), substitute the numerical values, we have:
h = P / (ρ * g) = 40,000 / (800 * 9.8) = 5.1 m
Answer: depth 5.1 m
