What is dynamic pressure?

 Basically, dynamic pressure is the pressure of a fluid such as a gas or liquid, which is the transfer of momentum from the molecules to the object on which the pressure acts. Dynamic pressure due to motion of fluid particle is known as collisional pressure. And this pressure is used to determine the airspeed of the aircraft. Dynamic pressure measurements are performed in various fields such as combustion control, automotive industry, turbo machinery and combustion analysis in aerodynamics in the process industry and power plants.
