WebThe drag coefficient is the number that describes how much. Going back to Figure 1, you can see that at Mach 3 (3348 fps), the G1 projectile has a drag coefficient of 0.51, while the G7 projectile has a drag coefficient of only 0.24. In the previous section we learned that at Mach 3, a .308 caliber bullet has 6.9 pounds of drag applied 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. It varies with the speed of airflow (or more generally with Reynolds number $${\displaystyle \mathrm {Re} }$$).
