What does Drag Coefficient mean in physical terms ? What is the significance of Drag Coefficient ?

Drag coefficient is a dimensionless number that depends on the projection area, fluid resistance and velocity. It is commonly denoted as Cd in aerodynamics calculations. Drag coefficient is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
