pressure drop
Sudden cabin alarm
Pressure drop is the decrease in pressure as a fluid flows through a system—a pipe, filter, valve, or other component.
Friction and turbulence cause the drop; the greater the resistance, the larger the pressure drop.
Engineers design systems to minimize pressure drop while maintaining flow: The clogged filter caused a significant pressure drop.
In HVAC, excessive pressure drop means fans work harder to move air.
