(provided by Paolo Papale)

Conditions:
bulletEtna trachybasalt
bulletTotal H2O: 2 wt%
bulletTotal CO2: 0.5 wt%
bulletT = 1373 K
bulletP range: 0.1 - 200 MPa

wH20 = 0.00026372 + 1.2604 10-9 P - 4.2158 10-17 P2 + 8.5836 10-25 P3 - 1.0996 10-32 P4 + 8.8151 10-41 P5 - 4.2637 10-49 P6 + 1.1333 10-57 P7 - 1.2681 10-66 P8
