Differential pressure

Differential Pressure

Differential pressure refers to the difference in pressure between two points in a fluid or gas-filled system. This difference in pressure can be measured and used to infer various properties of the system, such as flow rate or density.

One common application of differential pressure is in the measurement of airspeed, as described in the original text. In this case, the difference in pressure between the air entering an aircraft’s pitot tube and the static pressure of the surrounding air is used to determine how fast the aircraft is flying.

Other applications of differential pressure measurement include monitoring fluid flow rates in pipelines, assessing filter performance in air or water purification systems, and detecting leaks or blockages in pipes or tubes.

Overall, differential pressure is an important concept in engineering and physics, providing a valuable tool for measuring and analyzing fluid and gas systems.
