We have described how fluid velocity can greatly affect whether a fluid is flowing in the laminar or turbulent flow regime. However, other properties may affect fluid behavior. Consider the area of microfluidics $-$ a branch of fluid dynamics that deals with fluids being transported in small chambers, often on the micro$-$ or nano$-$ scale. For these systems, what flow regime usually dominates$-$laminar or turbulent flow? Explain your reasoning.
