The water pressure depends only on the depth, not on the size or shape of the vessel. The pressure increases at about 1 atmosphere (or bar) every 10 meters.

Twelve fathoms

500 acres is 21,780,000 square feet. Assuming dthe depth is greater than the width, the depth can be any number greater than sqrt(21780000) = 4666.91 ft. Suppose the depth is D feet then a rectangular area with width = 21780000/D will have an area of 21780000 sq ft or 500 acres.

Pressure in seawater at 100 feet is 44 psi. Or, .44 pounds per square inch per 1 foot. For Fresh water, it is .43 psi per foot.

Two atmospheres is 67.8 feet of water.

The water pressure at a depth of 300 feet would be approximately 130 psi. This calculation is based on the fact that water pressure increases by 0.433 psi for every foot of depth.

35000 feet of altitude exerts more pressure on an object compared to 260 feet of water depth. This is because the pressure exerted by the atmosphere decreases as altitude increases, while the pressure exerted by water increases as depth increases.

No. The pressure depends on the depth, and on the density of the liquid, which is presumably more or less the same in this case.

The water pressure at 5000 feet depth is approximately 2200 pounds per square inch (psi). This pressure increases by 0.44 psi for every foot of depth.

Water pressure at a depth of about 44 feet is about 20psi

Water pressure increases by about 1 atmosphere for every 33 feet of depth. At 2000 feet depth, the water pressure would be about 60 atmospheres or 882 psi (pounds per square inch). This high pressure can pose significant challenges for deep-sea exploration and engineering.

The pressure at 5400 feet underwater is approximately 2333 pounds per square inch (psi). At this depth, the water column above exerts a significant amount of pressure on any object or structure submerged at that depth.

As water depth increases, the pressure exerted by the water also increases. This is due to the weight of the water above pushing down on the water below. Pressure increases at a rate of about 1 atmosphere for every 10 meters of water depth.

About 21.4 psi

The water pressure of the ocean at 500 feet is approximately 217.5 pounds per square inch (psi). This pressure increases by 14.7 psi for every additional 33 feet in depth due to the weight of the water above.

300 feet of sea water exerts a pressure of approximately 130 psi.

The pressure at a depth of 200 feet of water is approximately 86.6 pounds per square inch (psi). This is calculated by dividing the depth (200 feet) by the specific gravity of water (0.433) to determine the pressure in psi.
