In aerodynamics, dynamic pressure (also known as “q” or “q∞”) is a measure of the kinetic energy of a moving fluid, such as air, per unit volume. It is a fundamental concept used to understand the forces acting on an object (like an aircraft) as it moves through the fluid.
- q is the dynamic pressure
- ρ (rho) is the density of the fluid (e.g., air) through which the object is moving
- V is the velocity of the object relative to the fluid
