What liquid is poured into a cylindrical vessel (determined by density) if it produces a pressure of 3720 Pa

What liquid is poured into a cylindrical vessel (determined by density) if it produces a pressure of 3720 Pa, and the height of its column is 40 cm?

Given: P (pressure produced by the liquid under consideration) = 3720 Pa; h (liquid column height) = 40 cm (SI h = 0.4 m).

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

To determine the density of the liquid under consideration, we use the formula: P = ρzh * g * h, whence ρzh = P / (g * h).

Let’s make a calculation: ρzh = 3720 / (10 * 0.4) = 930 kg / m3 (sunflower oil).

Answer: Sunflower oil was poured into the vessel.
