In the Challenger Deep of the Marianas Trench the depth of seawater is 10 9 km and the pressure is 1 16 x 108 Pa (about 1 15 x 103 atm)
Seawater density increases from 1 0240 g/cm3 at 20°C to 1 0273 g/cm3 at 0°C at a constant salinity Globally there is an average of about a 20°C temperature
What is the density of ocean water at a depth where the pressure is 80?
Hence, the density of the water at a depth where pressure is 80.0 atm is 1.034?3kg/m3.What is the density of seawater at this pressure?
One more way can be used when sea water salinity values are determined using density values equations of the following type: ? = f?(S, ?, ?).How do you calculate seawater density?
In fact, the average density of seawater is 1.0278g/cm³ (1.02677 g/cm³) which is 2 to 3 percent higher than the density of pure water (1.00g/ cm³) at 4°C temperature.
