Dynamic pressure
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 • Pressure • Pressure head • Hydraulic head • Total dynamic head • Drag, lift and pitching moment coefficients 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.
