The vessel is filled with liquid with a column height of 20 cm, while its pressure on the bottom

The vessel is filled with liquid with a column height of 20 cm, while its pressure on the bottom of the vessel turned out to be 1800 Pa. Determine the density of this liquid.

The pressure of the liquid column is calculated by the formula:

P = d * g * h, where

d is the density of the liquid, kg / m3;

g – acceleration of gravity, 9.8 m / s2;

h is the height of the liquid column, m.

20 cm = 0.2 m;

Let us express the density from the above formula.

d = P / (g * h) = 1800 / (9.8 * 0.2) = 918.4 kg / m3.

Answer: d = 918.4 kg / m3.
