dynamic pressure[dī¦nam·ik ′presh·ər]
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.
The 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.
The 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.
