water#

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

Calculates vapor pressure of pure water or seawater given by [1] based on Raoult’s law. The pure water vapor pressure is given by [2]

Parameters
  • %(models.target.parameters)s

  • %(models.phase.T)s

  • salinity (str) – The dictionary key containing the phase salinity values

Return type

%(models.phase.vapor_pressure.returns)s

Notes

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

thousand)

VALIDITY: 273 < T < 473 K; 0 < S < 240 g/kg; ACCURACY: 0.5 %
