Gotta account for:
Turbulence in freestream
Heating of fluid by surface
The Reynolds number is given by
Re = ( Rho[freestream] * V[freestream] * Xtransision )/ mu[freestream]
Rho is density
V is velocity
Xtransition is distance along surface
mu is viscosity
A rule of thumb is transition occurs around a Re of 500,000, but that will vary depending on the other factors mentioned above. Generally a flow of Re much less than 500,000 is laminar, and much above 500,000 is turbulent.
Hope this helps.
So for you:
Xtransition = (Re * Mu) / (rho * V)
