What is the pressure on a shark 500 feet below the surface of the ocean?

Water pressure increases at 0.433 psi per foot of depth, or slightly more for salt water, so at 500 feet it is in round figures 220 pounds per square inch. Of course, down there the shark has the same pressure inside it as outside, so it is perfectly comfortable.

1foot=0.3048 m

500foot=0.3048*500meter=152.4meter

hydrostatic law:

p=sp.gr.*h

p=1027 kg/m3*152.4meter

p=156514.8 kg/m^2

156 514.8 kilogram-force/square meter = 15.651 48 kilogram-force/square centimeter.

156 514.8 kilogram-force/square meter = 15.348 858 634 bar

156 514.8 kilogram-force/square meter = 15.148 144 209 atmosphere [standard]

156 514.8 kilogram-force/square meter = 15.651 48 atmosphere [technical]

156 514.8 kilogram-force/square meter = 222.616 373 73 pound/square inch.

(The density of pure water is 1000 kg/m3. Ocean water is more dense because of the salt in it. Density of ocean water at the sea surface is about 1027 kg/m3. There are two main factors that make ocean water more or less dense than about 1027 kg/m3. The first is the temperature of the water and the other us the salinity of the water. Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water. However, temperature has a greater effect on the density of water than does salinity. Hence, a layer of water with higher salinity can actual float on top of water with lower salinity if the layer with higher salinity is quite a bit warmer than the lower salinity layer. The temperature of the ocean decreases significantly as you go to the bottom of the ocean. So, the density of ocean water increases somewhat proportantly as you go to the bottom of the ocean. The deep ocean is layered with the densest water on bottom and the lightest water on top. Circulation in the depths of the ocean is horizontal. That is, water moves along the layers with the same density. The density of ocean water is rarely measured directly. If you wanted to measure the density of ocean water, you would have to collect a sample of sea water and bring it back to the laboratory to be measured. Density is usually calculated using an equation. You just need to measure the salinity, temperature and pressure to be able to find density. )

Should be about 16.2735123 kilograms per square centimeter.
