Default Eddy viscosity formulation

Dear all, I found the formula for Eddy viscosity in FLUENT manual is

DENSITY * C * KineticEnergy*KineticEnergy / DissipationRate.

But, in another literature for the same Standard K-E turbulence model, they have not including the Density in the above expression. In which case this formula will differ ??

If you see the following link, here, they have not included the Density part. http://w3.gre.ac.uk/~physica/phy3.00/theory/node152.htm

Kindly provide the clear idea regarding this issue. Thank you very much Raja...
