In incompressible fluid dynamics dynamic pressure (indicated with q, or Q, and sometimes called velocity pressure) is the quantity defined by:
where (using SI units):
-
= dynamic pressure in pascals, = fluid density in kg/m3 (e.g. density of air), = fluid velocity in m/s.

Famous quotes containing the words dynamic and/or pressure:
“The nearer a conception comes towards finality, the nearer does the dynamic relation, out of which this concept has arisen, draw to a close. To know is to lose.”
—D.H. (David Herbert)
“Amid the pressure of great events, a general principle gives no help.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
