In fluid dynamics, dynamic pressure (denoted by q or Q and sometimes called velocity pressure) is the quantity defined by: $${\displaystyle q={\frac {1}{2}}\rho \,u^{2}}$$where (in SI units): q is the dynamic pressure in pascals (i.e., kg/m/s ),ρ is the fluid mass density (e.g. in kg/m ), andu is the flow … See more Dynamic pressure is the kinetic energy per unit volume of a fluid. Dynamic pressure is one of the terms of Bernoulli's equation, which can be derived from the conservation of energy for a fluid in motion. It can also appear … See more Many authors define dynamic pressure only for incompressible flows. (For compressible flows, these authors use the concept of impact pressure.) However, the definition of … See more • Definition of dynamic pressure on Eric Weisstein's World of Science See more The dynamic pressure, along with the static pressure and the pressure due to elevation, is used in Bernoulli's principle as an energy balance on a closed system. The three terms are used to define the state of a closed system of an incompressible, constant-density fluid.
