total CO2 molecules in seawater communicate with the air via gas exchange across the sea surface. This quantity is called the partial pressure of CO2 (pCO2)

In sea water the concentration of water molecules in the solution is less than that of pure water so the vapor pressure of sea water is also lower The vapor pressure of pure water at 20 deg C is 0 0231 atm while the vapor pressure of seawater with the composition listed above is 0 0226 atm
Pressure also affects seawater density but only in the deepest parts of the ocean It is important to know about layering because it affects ocean currents Deep water currents are part of the global circulation of the Earth’s ocean
actual pressure required is approximately two times the osmotic pressure; for seawater this translates to about 800–1000 pounds per square inch (psi) (55–69 bar) This pressure multiplied by the incoming flow rate determines the minimum amount of power required to push water through a membrane Other processes such
What is the pressure at a certain depth in sea water?
Pressure at a certain depth in river water in p1 and at the same depth in sea water is p2 . Then (Density of sea water is greater than that of river water) :
What is the gas pressure of 33 ft of seawater?

The pressure exerted by 33 ft of seawater is equivalent to 1 atm pressure.
What is the pressure of water at different elevations?
At an elevation of 8,000 feet (2,438 meters), water boils at 197? (91?) and pressure is 10.9 psia. At an elevation of 10,000 feet (3,048 meters), water boils at 193? (89.6?) and pressure is 10.1 psia. Does the viscosity of a fluid change in different surfaces? The viscosity represents the resistance to one layer of fluid sliding over another.
How much pressure does a column of seawater exert?
A typical dive might be 40 to 65 ft, but dives to 90 ft are not uncommon. Because seawater has a slightly higher density than fresh water—about 1. 03 g/mL, compared with 1. 00 g/mL—the pressure exerted by a column of 33 ft of seawater is equivalent to 1 atm pressure.
