The tank is filled with gasoline to a height of 20 cm. Determine the force of pressure on the bottom

The tank is filled with gasoline to a height of 20 cm. Determine the force of pressure on the bottom of the tank with an area of 4 dm ^ 2.

To find the value of the pressure force of the gasoline layer at the bottom of the specified tank, we use the formula: F = P * S = ρb * g * h * S.

Constants and variables: ρb – gasoline density (we take ρb = 710 kg / m3); g – acceleration of gravity (g = 9.81 m / s2); h is the height of the gasoline layer (h = 20 cm = 0.2 m); S is the bottom area of the indicated tank (S = 4 dm2 = 4 * 10-2 m2).

Calculation: F = ρb * g * h * S = 710 * 9.81 * 0.2 * 4 * 10-2 ≈ 55.72 N.

Answer: A layer of gasoline presses on the bottom of the indicated tank with a force of 55.72 N.
