Unit error in Modelica.Mechanics.MultiBody.Examples.Loops.Utilities.GasForce2

For R_air:

  constant SI.SpecificHeatCapacity R_air = Modelica.Constants.R / 0.0289651159;

we should introduce the molar mass of air, if I am not mistaken.

Something like(?)

  constant SI.MolarMass MM_air = 0.0289651159;
  constant SI.SpecificHeatCapacity R_air = Modelica.Constants.R/MM_air;

Actually, I guess it shall be MM of a gas compound in a combustion engine. (But maybe not so important.)

[qlambert-pro]

That's what I had in mind. If we go by this proposal: modelica/ModelicaSpecification#3266, this is the sort of things tools should start rejecting.

[tobolar]

The fix shall be straightforward as the definition of R_air is protected.
