WebNotice that the drag coefficient is a dimensionless quantity. At highway speeds, over 50% of the power of a car is used to overcome air drag. The most fuel-efficient cruising speed is about 70–80 km/h (about 45–50 mi/h). The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag . See more 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 See more The drag equation $${\displaystyle F_{\rm {d}}={\tfrac {1}{2}}\rho u^{2}c_{\rm {d}}A}$$ is essentially a … See more Concept The force between a fluid and a body, when there is relative motion, can only be transmitted by … See more • Automotive aerodynamics • Automobile drag coefficient • Ballistic coefficient 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 direction of the flow velocity See more General In general, $${\displaystyle c_{\mathrm {d} }}$$ is not an absolute constant for a given body shape. It varies with the speed of airflow (or more generally with Reynolds number $${\displaystyle \mathrm {Re} }$$). A smooth sphere, … See more
