How much pressure does a 50 cm layer of gasoline exert on the bottom of the canister?

Initial data: h (height of the gasoline layer in the canister) = 50 cm (0.5 m).

Reference data: g (acceleration due to gravity) ≈ 10 m / s2; by condition ρb (gasoline density) = 700 kg / m3.

The pressure of the gasoline layer at the bottom of the canister is calculated by the formula: P = ρb * g * h.

Let’s make a calculation: P = 700 * 10 * 0.5 = 3500 Pa (3.5 kPa).

Answer: A layer of gasoline exerts a pressure of 3.5 kPa on the bottom of the canister.
