effective viscosity in RNG k-e turbulence model

I need to calculate the effective viscosity when using the RNG k-e model, and I have two questions:

1. A differential equation for the effective viscosity calculation is provided in Yakhot's paper where the origin of the RNG k-e model was discussed, but I found that the formulation of this equation is different from the one that's given in Fluent manual. I don't know why and which one is correct.

2. In the equation provided by Yakhot, the value of a constant C is not given explicitly. I found it might be 75, but not sure.

Could someone please give me an answer to these? I'd appreciate it very much.
