#30# times per second or #1,800# times per minute

Explanation:

This number may seem low compared to other flying insects however this is purely due to the large surface area and breadth of its wings. It provides it with the ability to successfully produce thrust and fly.

We can also say that dragonflies have around #4000 R_e#. #R_e# represents Reynold's Number . This is a measure of inertial forces that can specify whether the flow of fluids past a body is steady or turbulent .
