water(target, temperature='pore.temperature', salinity='pore.salinity')[source]#

Calculates density of pure water or seawater at atmospheric pressure using Eq. (8) given by Sharqawy et. al [1]. Values at temperature higher than the normal boiling temperature are calculated at the saturation pressure.

  • %(models.target.parameters)s

  • %(models.phase.T)s

  • salinity (str) – Name of the dictionary key on target where the array containing salinity values is stored.

Return type



T must be in K, and S in g of salt per kg of phase, or ppt (parts per


VALIDITY: 273 < T < 453 K; 0 < S < 160 g/kg; ACCURACY: 0.1 %
