Pressure measured in a housing or duct through an hole in a wall parallel to the direction of flow.
The pressure of a fluid at rest, or in motion, exerted perpendicularly to the direction of flow.
the pressure in a fluid at rest.
force (per unit area) expended against the walls of a container such as an air duct; commonly force is measured in heating and air conditioning in pounds per square inch, or inches of water pressure
The pressure measured in a flowing stream in such a manner that the velocity of the stream has no effect on the measurement.
In flowing air, the total pressure minus velocity pressure. The portion of the pressure that pushes equally in all directions.
The potential pressure exerted in all directions by fluid at rest. For a fluid in motion, it is measured in a direction normally 90° to the direction of flow. Usually expressed in inches water gauge when dealing with air.
The pressure of a gas measured at a point where the gas velocity is zero.
