The height of the kerosene in the tank can be calculated from the formula:
P = ρ * g * h, where P is the specified pressure of kerosene at the bottom of the tank (P = 1600 Pa), ρ is the density of kerosene (according to the table, ρ = 800 kg / m3), g is the acceleration of gravity (we take g = 10 m / s2), h is the desired height of kerosene in the tank.
Let us express from the formula and calculate the height of the kerosene in the tank:
h = P / (ρ * g) = 1600 / (800 * 10) = 0.2 m = 20 cm.
Answer: The height of the kerosene in the tank is 0.2 m or 20 cm.
