Reynolds number formula¶
Reynolds number is a dimensionless quantity that characterizes the flow of a fluid. It helps predict fluid flow patterns in different situations by measuring the ratio between inertial and viscous forces. Low Reynolds numbers tend to correspond to laminar flows, while high Reynolds numbers tend to correspond to turbulent flows.
