What is the pressure inside a liquid with a density of 900 kg / m3 at a depth of 20 cm?

To find out the pressure inside the specified liquid, we use the formula: Phydr = ρl * g * h, where ρl is the density of the specified fluid (ρl = 900 kg / m3); g – acceleration due to gravity (g ≈ 9.8 m / s2); h is the considered depth (h = 20 cm; in SI h = 0.02 m).

Let’s perform the calculation: Phydr = ρl * g * h = 900 * 9.8 * 0.2 = 1764 Pa.

Answer: The required pressure inside the specified fluid should be 1764 Pa.
