In fluid dynamics, dynamic pressure (denoted by q or Q and sometimes called velocity pressure) is the quantity defined by: q = 1 2 ρ u 2 {\displaystyle q={\frac {1}{2}}\rho \,u^{2}} where (in SI units): q is the dynamic pressure in pascals (i.e., N/m2), ρ (Greek letter rho) is the fluid mass density (e.g. in kg/m3), and u is the flow speed in m/s.
