In an open tank filled up to the level of 4m. be liquid. its pressure on the bottom of the cistern is 28 kPa. the density of this fluid is a wound?

The pressure at the bottom of the vessel is determined by the following formula:

P = ρgh, where ρ is the density of the liquid, g is the acceleration of gravity, h is the distance from the bottom to the surface of the liquid.

We find the density of the liquid ρ:

ρ = P / gh = (28,000 Pa) / (10 m / s ^ 2 * 4 m) = (28,000 N / m ^ 2) / (40 m ^ 2 / s ^ 2) = ((700 kg * m) / (c ^ 2 * m ^ 2)) * (c ^ 2 / m ^ 2) = 560 kg / m ^ 3.

Answer: 560 kg / m ^ 3.
