What is the salinity equation?

Calculate salinity, using the formula: salinity (ppt) = 0.0018066 5 Cl– (mg/L).

How is density and temperature related?

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

Can you calculate salinity from conductivity?

Raise the conductivity (in mS/cm) to the power 1.0878. Multiply the result by 0.4665. This gives you salinity in grams (of salt) per liter (of solution).

How does temperature affect water density?

When the water is heated, it expands, increasing in volume. The warmer the water, the more space it takes up, and the lower its density. When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense.

How do you find density with 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.

How do you calculate conductivity and salinity from temperature?

Does mass change with temperature?

In almost every chemistry and introductory physics textbook you’ll find the answer to this is that temperature has absolutely no effect on mass. In normal situations and to normal precision, mass is completely unchanged when you add energy to a system.

How do you find density with only temperature?

If you know density ρr at some temperature Tr, there is a following formula for density: ρ=ρr[1+b(T−Tr)], where ρ is the density at temperature T and b is called coefficient of cubical expansion, evaluated at reference temperature and density (ρr and Tr).
