Reynolds number is the ratio of the fluid speed to some characteristic speed, $v_R = \frac{\mu}{\rho L}$ where $L$ is some characteristic length scale of the situation.

Is there an intuitive interpretation or some kind of physical picture of what this speed $v_R$ means?

Is there an intuitive interpretation or some kind of physical picture of what this speed $v_R$ means? Is there any interpretation beyond "the speed above which turbulence arises"?
