What is the density of seawater?

What is the density of seawater?

Density of seawater and pressure

depth (m) pressure (decibars) density (g/cm3)
0 0 1.02813
1,000 1,000 1.03285
2,000 2,000 1.03747
4,000 4,000 1.04640

What is the molar mass of seawater?

The mean molecular weight of pure water over the range 0–40 °C is 86.1–80.7 and 89.4–84.5 for seawater.

What is the density of ocean water kg m3?

1026 kg/m3
Since fresh water weighs about 1000 kilograms per cubic meter and seawater weighs about 1.026 times that, we say that the typical seawater density is 1026 kg/m3.

What is the density of seawater in LB ft3?

65 lb/ft3
65 lb/ft3 or 8.68 lb/gal (1.04 g/cc).

What kind of seawater is densest?

The densest ocean water is formed in two primary locations near the poles, where the water is very cold and highly saline as a result of ice formation. The densest deep water mass is formed in the Weddell Sea of Antarctica, and becomes the Antarctic Bottom Water (AABW).

What is the density of saltwater in g cm3?

1.03 g/cm3
Density refers to the amount of mass per unit volume, such as grams per cubic centimeter (g/cm3). The density of fresh water is 1 g/cm3 at 4o C (see section 5.1), but the addition of salts and other dissolved substances increases surface seawater density to between 1.02 and 1.03 g/cm3.

What is the concentration of salt in seawater?

about 35 parts per thousand
The concentration of salt in seawater (its salinity) is about 35 parts per thousand; in other words, about 3.5% of the weight of seawater comes from the dissolved salts.

How do you find the density of seawater from temperature and salinity?

It can be approximated as: ΔDensity = α*ΔT+β*ΔS α and β are coefficients of thermal expansion and saline contraction. α is roughly 0.2 kg m-3 °C-1 β is roughly 1 kg m-3 psu-1 These values are where the 15°C and 3 psu come from. In the ocean, α and β also depend on salinity, temperature, and pressure.

What is the density of saltwater vs freshwater?

Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume.

Is lb ft3 a density?

“lb/ft3″ simply means “pounds per cubic foot”, and it means density. “Pounds” used to be mass. But now it is a measure of force, and the “slug” is a measure of mass.

What is the density of seawater in PPG?

The density in pounds per gallon, or PPG, for average seawater is 8.68 lb/gal or 1.04 g/mL which is standard temperature and pressure.
