Given any flow restrictive device (e.g. pipe, orifice, screen, etc.) one can measure data as the pressure drop across the device relative to the flow rate through the device. And from this data one can generally closely fit the polynomial
$$\Delta P = K_2Q^2+K_1Q $$
where $\Delta P$ is the pressure drop and $Q$ is the volumetric flow rate
Furthermore there have been people that (I believe) mis-appropriately attribute these factors to concepts involving Reynolds number, calling, for example $K_2$ the 'turbulent' flow factor and $K_1$ the 'laminar' flow factor.
While it is true that $K_1$ dominates the pressure drop at low flow, and $K_2$ dominates at high flow, I don't believe there is any basis to attribute these empirical factors to laminar and turbulent flow characteristics.
Am I maybe missing something? Is there anything in the analysis of fluid dynamics that might support such a naming convention or otherwise refute it?
