Determine Laminar flow

For practical purposes, if the Reynolds number is less than 2000, the flow is laminar. If it is greater than 3500, the flow is turbulent. Flows with Reynolds numbers between 2000 and 3500 are sometimes referred to as transitional flows.

Explanation:

Turbulence appears when the Reynolds number is about 2300. Reynolds number = (density * D * flow speed) / viscosity. Details of the calculation: Reynolds number = (1.25 kg/m3)*(0.1 m)*(35 m/s)/(1.83*10-5 N s/m2) = 2.39*105.
