- Air free water
- Air saturated water
This option is used to select whether the correction for air saturated water is made or not.
Density of Air-Free Water
The density of air-free water is calculated by:
|ρ0||=||999.97358 (Maximum density of water (at t0))|
|A||=||7.0134 x 10-8 °C-1|
|B||=||7.926504 x 10-6 °C-2|
|C||=||-7.575677 x 10-8 °C-3|
|D||=||7.314894 x 10-10 °C-4|
|E||=||-3.596458 x 10-12 °C-5|
Correction for Air-Saturated Water
The correction for air-saturated water is:
This is then added onto the density of air free water to give the density for air saturated water.
