Gas constant value properties

An example to define a gas with constant properties is given below:

EOS GAS
  SURFACE_DENSITY 1.87 kg/m^3
  FORMULA_WEIGHT 44.0 g/mol
  DENSITY CONSTANT 11.00 !defaults to kmol/m3, unit cannot be specified.
  VISCOSITY CONSTANT 0.0395 cP
  ENTHALPY CONSTANT 1.8890d0 J/kmol
END

Except for Density, the units are optional. If not entered they will take the following defaults:

• enthalpy units : \(J/k\mbox{mol}\)

• viscosity units : \(Pa.s\)

• density units are \(\mbox{kmol}/m^3\), and units cannot be specified.
