Dynamic pressure refers to the kinetic energy per unit volume of a fluid in motion. It is a measure of the pressure exerted by the fluid due to its motion. It characterizes the pressure exerted by the airflow due to its motion and is a critical parameter for understanding and analyzing the aerodynamic behavior of the aircraft. Mathematically, dynamic pressure, denoted as , is given by:
Where:
- = dynamic pressure at freestream condition in pascals
- = density in kg/m3
- = freestream velocity in m/s
