Here, the C_{D} in different flow regimes is summarized in the chart below. 1. Newton's Law: mainly applicable to the turbulent regime (Re_{p} > 1000), where viscous forces are negligible compared to inertial forces. 2. Stokes's Law: valid in the laminar flow regime (Re_{p} < 1), where inertial forces are negligible compared to viscous forces. 3. Transition region: between the laminar and turbulent flow regime.
