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 pressure and/or dynamic:
“Under the pressure of the cares and sorrows of our mortal condition, men have at all times, and in all countries, called in some physical aid to their moral consolations—wine, beer, opium, brandy, or tobacco.”
—Edmund Burke (1729–1797)
“Imagination is always the fabric of social life and the dynamic of history. The influence of real needs and compulsions, of real interests and materials, is indirect because the crowd is never conscious of it.”
—Simone Weil (1909–1943)
