Question
Hello, I was wondering if you could tell me the typical drag coefficient of a tranquilizer dart.

Answer
Mohammad - Sorry for the delay, but I have been doing a little literature search on your question.  I am pretty sure that the dart body, assuming it is a cylinder with a faired nose, has a drag coefficient of approximately 0.2 based on the cross-sectional area (Hoerner's data).  But there will be a little more from the tail fleche.  If I can find that I will send you a followup answer.
