water¶
- openpnm.models.phases.vapor_pressure.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
- Returns
- 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 %
