Dynamic pressure facts for kids
In fluid dynamics dynamic pressure depends on density and velocity of the fluid.
It is defined by the following equation (with q standing for dynamic pressure or "velocity pressure"):
where (using SI units):
- = dynamic pressure in pascals
- = fluid density in kg/m3 (such as the density of air)
- = fluid velocity in m/s

-
A flow of air through a venturi meter, showing the columns connected in a U-shape (a manometer) and partially filled with water. The meter is "read" as a differential pressure head in cm or inches of water and is equivalent to the difference in velocity head.
