Water is poured into an aquarium 32 cm high, 50 cm long and 20 cm wide, the level of which is 2 cm below the edge. Calculate the water pressure at the bottom of the aquarium without water.

To calculate the amount of water pressure at the bottom of the presented aquarium, we apply the formula: P = ρw * g * h = ρw * g * (ha – Δh).

Constants and variables: ρw is the density of the aquarium water (ρw = 1000 kg / m3); g – acceleration due to gravity (g ≈ 10 m / s2); ha – the height of the aquarium (ha = 32 cm = 0.3 m); Δh is the height between the edge of the aquarium and the surface of the water (Δh = 2 cm = 0.02 m).

Let’s make a calculation: P = ρw * g * (ha – Δh) = 1000 * 10 * (0.32 – 0.02) = 3 * 103 Pa.

Answer: Aquarium water creates a pressure of 3 kPa at the bottom.
