| **Calculate the oil pressure at the bottom of the tank if its level is 9.5 m from the bottom. Also determine the total force of pressure on the bottom, the area of which is 290 m2**

Initial data: h (oil height in the tank) = 9.5 m; S (bottom area of the oil tank) = 290 m2.

Reference data: g (acceleration due to gravity) ≈ 10 m / s2; ρн (oil density) = 800 kg / m3.

1) Let’s calculate the oil pressure at the bottom of the tank: Р = ρн * g * h = 800 * 10 * 9.5 = 76,000 Pa (76 kPa).

2) Determine the total force of oil pressure on the bottom of the tank: F = P * S = 76,000 * 290 = 22,040,000 N = 22.04 MN.

Answer: The oil pressure at the bottom of the tank is 76 kPa, and the total oil pressure force is 22.04 MN.
