The tank is filled with liquid, the height of the tank is 150 cm, and the pressure exerted by the liquid is 10650 Pa. Find the density of the liquid.

Initial data: h (the height of the tank, the height of the desired liquid column) = 150 cm; P (pressure exerted by the desired liquid on the bottom of the tank) = 10650 Pa.

Constants: g = 10 m / s ^ 2.

SI system: h = 150 cm = 150/100 m = 1.5 m.

We express the density of the liquid from the following formula:

P = ρ * g * h and ρ = P / (g * h).

Let’s calculate the density of the unknown liquid:

ρ = 10650 / (10 * 1.5) = 710 kg / m ^ 3 (corresponds to the density of gasoline or ether).

Answer: According to the calculation, the density of the liquid is 710 kg / m ^ 3.
