Ups I missed that Alchemy didn't use kinematic viscosity, but rather dynamic viscosity; kinematic visc. = dyn. visc. / denstity.
So that's the same equation.
But I agree that lamilar flow cant' occur in waterblock. As I know lamilar flow is actualy very hard to achieve, but there is rather more turbolent or less turbolent flow. Unideal surface quality has a lot to do with this too.
Definition of Laminar flow is following: this is the flow where particles are moving in infinetly thin layers which slides between themself without mixing .
With turbolent flow particles are moving iregulary in all directions
I hope I wrote correctly so it is understandable (english isn't my native language)
