What is the water pressure on the bottom of a rectangular aquarium 2 m long, 1 m wide, 50 cm deep

What is the water pressure on the bottom of a rectangular aquarium 2 m long, 1 m wide, 50 cm deep, filled to the brim with water?

To solve this problem, it is not necessary to determine the volume of water in a given aquarium, since the pressure does not depend on the volume, but depends solely on the depth of the aquarium.

We translate the depth into meters.

50 cm = 50/100 = 0.5 m.

As you know, the density of water is: p = 1000 kg / m3.

To determine the pressure at the bottom of the aquarium, we use the following formula:

P = p * g * h,

Where:

P is the pressure on the bottom of the aquarium;

p is the density of water;

g – gravity (constant number 9.8 m / s2);

h is the depth of the aquarium.

Substitute the known values ​​into the formula:

P = 1000 * 9.8 * 0.5 = 9800 * 0.5 = 4900 Pa.

Answer: The pressure at the bottom of the aquarium is 4900 Pa.
