In fluid dynamics, the drag coefficient (commonly denoted as: $${\displaystyle c_{\mathrm {d} }}$$, $${\displaystyle c_{x}}$$ or $${\displaystyle c_{\rm {w}}}$$) 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 … See more The drag coefficient $${\displaystyle c_{\mathrm {d} }}$$ is defined as where: • $${\displaystyle F_{\mathrm {d} }}$$ is the drag force, which is by definition the force component in the … See more General In general, $${\displaystyle c_{\mathrm {d} }}$$ is not an absolute constant for a given body shape.
