Dynamic pressure, often denoted as “q,” is a term used in fluid dynamics and aerodynamics to describe the pressure exerted by a fluid (such as air or a gas) in motion. It represents the kinetic energy per unit volume of the fluid due to its motion and is a fundamental concept in the study of fluid flow, especially in the context of aircraft, spacecraft, and other moving objects.
- q represents dynamic pressure.
- ρ (rho) is the density of the fluid.
- V is the velocity of the fluid relative to the object or reference point.
