Dynamic pressure (sometimes called velocity pressure) is the increase in a moving fluid's pressure over its static value due to motion. In incompressible fluid dynamics, it is indicated as q, or Q, defined by: q=(ρ u²)/2 where (using SI units): q = dynamic pressure in pascals, ρ = fluid density in kg/m³ (e.g. density of water), u = flow speed in m/s.
