5.2 Drag Forces - College Physics 2e OpenStax
WebTable 5.2 lists some typical drag coefficients for a variety of objects. Notice 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). WebAny object moving through a fluid experiences drag - the net force in the direction of flow due to pressure and shear stress forces on the surface of the object. The drag force can be expressed as: Fd = cd 1/2 ρ v2 A (1) where Fd = drag force (N) cd = drag coefficient ρ … Rolling Resistance - Drag Coefficient - Engineering ToolBox Car - Drag Coefficient - Engineering ToolBox Related Topics . Fluid Mechanics - The study of fluids - liquids and gases. … Liter/100 Km - Drag Coefficient - Engineering ToolBox In fluid dynamics, the drag coefficient (commonly denoted as: , or ) 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 coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particula… nes fircroft process engineer
