Determine the density of the milk poured into the can, if the pressure on the bottom is 10 kPa, and the height of the can is 1 m.

In accordance with the basic law of hydrostatics, the pressure P of a fluid with density ρ at a depth h {\ displaystyle h} h is equal to

P = ρ * g * h,

where g = 10 m / s² is the gravitational acceleration at the Earth’s surface.

Let us express the required milk density:

ρ = P / (g * h).

Substitute the known values and find the density of milk:

ρ = 10000 / (10 * 1) = 1000 kg / m³.
