Calculate the pressure that kerosene exerts on the bottom of a 5 square meter tank. The mass of kerosene in a tank is 500 kg.

Initial data: S (area of the bottom of the tank with kerosene) = 5 m2; m (mass of kerosene in the tank) = 500 kg.

Reference data: g (acceleration due to gravity) ≈ 10 m / s2.

The pressure that 500 kg of kerosene will have on the bottom of the tank can be calculated using the formula: P = F / S = m * g / S.

Let’s make the calculation: P = 500 * 10/5 = 1000 Pa (1 kPa).

Answer: The mass of kerosene exerts a pressure of 1 kPa on the bottom of the tank.
