Determine the density of the liquid if there is a pressure of 1600Pa at a depth of 20 cm.

These tasks: h (the height of the column of the liquid under consideration) = 20 cm (0.2 m); P (fluid pressure) = 1600 Pa.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

We express the density of the liquid under consideration from the formula: P = ρzh * g * h, whence ρzh = P / (g * h).

Let’s make a calculation: ρzh = 1600 / (10 * 0.2) = 800 kg / m3.

Answer: The density of the liquid in question is 800 kg / m3.
