The drag resistance (D) of a projectile depends on its diameter (d), its velocity (V), fluid density (p) and viscosity (H), and bulk modulus (k). Prove that D= C, ApV² where CD is the coefficient of drag and A is the biggest cross-sectional area of the projectile perpendicular to the flow direction.
