Is laminar a flow?

Laminar flow is defined as the movement of liquids without turbulences. The fluid flows in parallel layers with no disruption between them. Laminar flow can be subdivided into the following: Unidirectional laminar flow.

What is the minimum amount of time that hands be washed prior to compounding?
