Dynamic pressure can be calculated by using the relation,
Dynamic Pressure=( ρV^2)/2
It’s nothing but kinetic energy per unit volume of flow. Velocity profiles of air stream reorganize at locations like nozzles, orifices, gates, and coils. etc following the formation of vortices/eddies resulting in the conversion of kinetic energy into heat. As a result, dynamic pressure is reduced.
