Chapter Assumptions

Unless stated otherwise, use the following values:

Atmospheric pressure at the Earth's surface: Patm = 1.013×10^5 Pa

Density of pure water = 1000 kg/m^3

Density of seawater = 1030 kg/m^3

“Standard temperature and pressure” means 0°C and the atmospheric pressure stated above.
