Drag factor units

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 Concept The force between a fluid and a body, when there is relative motion, can only be transmitted by normal pressure and tangential friction stresses. So, for the whole body, the drag part of the force, which is in-line with … See more The drag equation $${\displaystyle F_{\rm {d}}={\tfrac {1}{2}}\rho u^{2}c_{\rm {d}}A}$$ is essentially a … 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 • Automotive aerodynamics • Automobile drag coefficient • Ballistic coefficient See more WebViewing Drag Factor. Drag factor is a measure of fan load.

WebFeb 2, 2024 · Where, C is the drag coefficient, which is dimensionless with values depending upon the shape of the object. (For example, C = 0.47 for a sphere and C = … In fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between an fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and …

WebThere are many factors which influence the amount of aerodynamic drag which a body generates. Drag depends on the shape, size, inclination, and flow conditions of the air passing the object. For a three dimensional … WebFeb 20, 2024 · The drag both between adjacent layers of fluid and between the fluid and its surroundings forms swirls and eddies, if the speed is great enough. We shall concentrate on laminar flow for the remainder of this section, leaving certain aspects of turbulence for later sections. Figure 12.4.2: (a) Laminar flow occurs in layers without mixing.
