dynamic pressure
dynamic pressurePressure resulting from some medium in motion, such as the air following the shock front of a blast wave.dynamic pressure
dynamic pressure[dī¦nam·ik ′presh·ər] (fluid mechanics) The pressure that a moving fluid would have if it were brought to rest by isentropic flow against a pressure gradient. Also known as impact pressure; stagnation pressure; total pressure. The difference between the quantity in the first definition and the static pressure. dynamic pressureThe pressure on the inner surface of a pipe when water flows through it; this pressure is in excess of that when the water is at rest.dynamic pressureThe pressure of a fluid resulting from its motion, equal to one-half the fluid density (ρ) times the fluid velocity (v) squared (q = ¼ρV2). In aerodynamic calculations, dynamic pressure is represented by the symbol q.AcronymsSeedata pump |
