Editing Drag coefficient (section)

=== General ===
In general, <math>c_\mathrm d</math> is not an absolute constant for a given body shape. It varies with the speed of airflow (or more generally with [[Reynolds number]] <math>\mathrm{Re}</math>). A smooth sphere, for example, has a <math>c_\mathrm d</math> that varies from high values for [[laminar flow]] to 0.47 for [[turbulent flow]].  Although the drag coefficient decreases with increasing <math>\mathrm{Re}</math>, the drag force increases.
