WebSep 19, 2024 · A velocity pressure (or dynamic pressure) indicated by q in incompressible fluid dynamics is defined as: q=\frac {1} {2}\rho u^2 In the equation above, q is measured in pascals (or kgm −1 s −2 ). ρ is fluid density (in kg/m 3) and u is the velocity of flow (in m/s). Static Pressure Pressure is an essential concept in fluid science. 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 (Greek letter rho) is the fluid mass density (e.g. in kg/m ), andu … 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. See more Many authors define dynamic pressure only for incompressible flows.
