How is the drag coefficient related to aerodynamic drag?
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 particular surface area. The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag.
What’s the coefficient of drag on an Acura NSX?
Vehicle CdA Make Model Year Cd Frontal Area (ft^2) Acura CL 1997 – 1999 0.34 21.6 Acura CL 2000 – 2003 0.32 22.0 Acura Integra 1994 – 2001 0.32 19.5 Acura NSX 1995 – 2005 0.32 19.2
Is the drag coefficient independent of Mach number?
For certain body shapes, the drag coefficient only depends on the Reynolds number , Mach number and the direction of the flow. For low Mach number , the drag coefficient is independent of Mach number. Also, the variation with Reynolds number within a practical range of interest is usually small,…
How big is the universal remote transmitter on a Mazda CX-9?
20.1 gal. 20.1 gal. 20.1 gal. universal remote transmitter (for garage door, security system, etc.) 0.35 cd. 0.35 cd. 0.35 cd.
How does the size of the car affect the drag coefficient?
While they do not have the biggest impact on the drag coefficient due to their small size, radio antennas commonly found protruding from the front of the vehicle can be relocated and changed in design to rid the car of this added drag.
20.1 gal. 20.1 gal. 20.1 gal. universal remote transmitter (for garage door, security system, etc.) 0.35 cd. 0.35 cd. 0.35 cd.
How does a side mirror affect the drag coefficient?
Side mirrors. Side mirrors both increase the frontal area of the vehicle and increase the coefficient of drag since they protrude from the side of the vehicle. In order to decrease the impact that side mirrors have on the drag of the vehicle the side mirrors can be replaced with smaller mirrors or mirrors with a different shape.
How does a boattail affect the drag coefficient?
A boattail can greatly reduce a vehicle’s total drag. Boattails create a teardrop shape that will give the vehicle a more streamlined profile, reducing the occurrence of drag inducing flow separation.
