A tank filled with oil has a depth of 4 m. Determine the pressure at the bottom of the tank.

To find the pressure of a column of oil in 4 m at the bottom of the indicated tank, we apply the formula: P = ρн * g * h.

Constants and variables: ρн – oil density (ρн = 800 kg / m3); g – acceleration of gravity (g = 9.81 m / s2); h is the depth of the indicated tank (h = 4 m).

Calculation: P = ρн * g * h = 800 * 9.81 * 4 = 31 392 Pa.

Answer: Oil exerts a pressure of 31 392 Pa at the bottom of the indicated tank.
