The pressure required to accelerate air from zero velocity to a greater velocity. It is proportional to the kinetic energy of the air stream.
Velocity pressure results only when air is in motion and is measured in inches of water (Pa). One inch water gauge corresponds to 4005 fpm (standard air) velocity. To determine velocity pressure use the following formula
The pressure caused by the velocity of air moving in the direction of flow. See also static pressure and total pressure.
Velocity pressure is the force per unit area capable of causing an equivalent velocity in a moving fluid. It exists by virtue of the gas density and velocity alone.
Same as dynamic pressure, wind pressure.
The amount of pressure in a circulation or ventilation system resulting from air movement.
The measure of kinetic energy of a fluid.
