Aquarium measurements long, wide and depth.

(a)

Find the hydrostatic pressure on the bottom of the aquarium:

Hydrostatic pressure is defined as .

Where and is depth of the water container in feet.

.

Substitute and in the above  formula.

.

Hydrostatic pressure on the bottom of the aquarium is .

(b)

Find the hydrostatic force  on the bottom of the aquarium:

Hydrostatic force is defined as .

Where is the area of the container and is hydrostatic pressure on the bottom of the container.

Bottom area of the aquarium is .

Substitute and in .

.

Hydrostatic force  on the bottom of the aquarium is .

(c)

 Find the hydrostatic force  on one end of the aquarium:

.

, where is the depth of the aquarium.

Strip area is , as depth increases then also increases.

Thus, consider width as .

 Hydrostatic force  on one end of the aquarium is .

(a) Hydrostatic pressure on the bottom of the aquarium is .

(b) Hydrostatic force  on the bottom of the aquarium is .

(c) Hydrostatic force  on one end of the aquarium is .
