Water density linear model¶
See Example below:
EOS WATER
SURFACE_DENSITY 1004.0 kg/m^3
DENSITY LINEAR 1000.0 1.0D7 4.6D-10
END
Note that in the example above, IFC67 default models are used for viscosity and enthalpy, because no other models are specified.
The three values entered are, in order:
The reference density, \(\rho_{ref}\), units kg/m^3
The reference pressure, \(P_{ref}\), units Pa
The water compressibility, \(C\), units 1/Pa
These values are used in the following model. The density is computed as:
\[\rho( P)=\rho_{\mbox{ref}} [1+C (P− P_{\mbox{ref}})]\]
Units cannot be entered and the values must be entered in the units reported above.
