Excellent, look forward to playing with them.

If you're asking for a graph of the relationship between viscosity and performance drop, I don't have one.
With water, the turbulence enhancement appears to offer around a 20% improvement in h over the closest equivalent mathematical model. That 20% is mostly emperically determined.
I roughly predict that the 5x more viscous liquid would roughly reduce that gain over the standard model to around 5-8% above what the standard model would predict for h for that level of viscosity.
Again, not plotted. Am more interested in emperical evidence and formulating rough theory, than attempting to assume that I have a hard theory that works.
