# Constant Value Oil Properties¶

This option assigns constant values to the density and viscosity that do not change with pressure and temperature. See example below:

EOS OIL
DENSITY CONSTANT 734.29d0 !kg/m3
ENTHALPY LINEAR_TEMP 1.d3 !c oil [J/kg/°C]
VISCOSITY CONSTANT 0.987d-3 !Pa.s
END


In the example above a linear model for the enthalpy is used.

The units are optional, if not entered will default to $$kg/m^3$$ for the density and to $$Pa.s$$. for the viscosity.
