Find the pressure that the kerosene exerts on the bottom of the tank if the height

Find the pressure that the kerosene exerts on the bottom of the tank if the height of the kerosene layer in the tank is h = 20 cm.

To find out the required pressure that a layer of poured kerosene exerts on the bottom of the used tank, we apply the formula: Phydr = ρк * g * h.

Const (according to the condition): ρк – density of kerosene in the tank (ρк = 800 kg / m3); g – acceleration due to gravity (g ≈ 10 m / s2).

Data: h is the height of the poured kerosene layer (h = 20 cm, in the SI system h = 0.2 m).

Let’s perform the calculation: Phydr = ρk * g * h = 800 * 10 * 0.2 = 1.6 * 10 ^ 3 Pa.

Answer: At the bottom of the used tank, kerosene must exert a pressure of 1.6 kPa.
