Drag coefficient

In fluid dynamics, the drag coefficient (commonly denoted as: c d {\displaystyle c_{\mathrm {d} }} , c x {\displaystyle c_{x}} or c w {\displaystyle c_{\rm {w}}} ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag…
