# Drag Coefficient of a rounded nose cylinders

How can the drag coefficient ($$C_D$$) of a cone follow a cylindrical body (as seen in the example be computed? Are there any analytical methods to compute the drag coefficient without doing any experiments ?
• No. To my knowledge $C_D$ can only be calculated for very, very low $\mathrm{Re}$ numbers (see Stokes' Law). For any realistic speeds, only empirical measurement can determine the value. – Gert Apr 22 at 15:18
