What liquid is poured into the vessel if it produces a pressure of 2840 Pa, and the height of its column is 40 cm?

Initial data: P (pressure that the liquid produces at the bottom of the vessel) = 2840 Pa; h (height of the liquid column that is poured into the vessel) = 40 cm.

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

SI system: h = 40 cm = 0.4 m.

The liquid is determined by the value of its density from the formula: P = ρ * g * h, whence ρ = P / (g * h).

Let’s make a calculation: ρ = 2840 / (10 * 0.4) = 710 kg / m3.

Answer: The obtained density value corresponds to gasoline or liquid ether.
