Turbulent flows are random in the sense that it is not possible to determine how fast a flow thing has at a certain place at a certain time, however it is statistically descriptive.
The higher the Reynolds number is, the more sensitive the flow is for disturbances. In turbulent flow, vortices are created that convert motion energy into thermal energy, which means that the heat losses in a turbulent flow are higher than in a laminar.
Laminar flow is linear, which means that they calculate the difference from the turbulent. Laminar flows give rise to lower heat losses and friction than the turbulentflöde.

The Reynolds number is a dimensionless quantity used in fluid mechanics to calculate whether media is flowing laminar or turbulent. At a Reynolds number of less than 2100, the flow is laminar, while if it exceeds 4000 so the flow is turbulent and in between is a mix between the two.
Reynolds number can be seen as the ratio of inertial forces and friction forces, where tubulent flow is dominated by inertial forces.
