1 Scope
This standard specifies common terms used in aircraft environmental control systems.
This standard applies to aircraft environmental control systems.
2 Terms and definitions
2.1 Comprehensive terms
2.1.1 Pressure
2.1.1.1 Pressure
Force acting on unit area.
[GB/T 30206.1-2013, definition 2.28]
2.1.1.2 Atmospheric pressure
The absolute pressure of the atmosphere in a given area and time.
[GB/T 30206.1-2013, definition 2.4]
2.1.1.3 Static pressure
The pressure of the fluid in addition to the effect of flow rate.
[GB/T 30206.1-2013, definition 2.51]
Note. The pressure measured by the device with zero velocity relative to the fluid. The pressure measured by the device perpendicular to the direction of fluid flow is approximately equal to this pressure.
2.1.1.4 Dynamic pressure
A recoverable pressure that rises or falls somewhere in a fluid for some reason.
[GB/T 30206.1-2013, definition 2.14]
Note. When the fluid flow rate drops to zero, the maximum static pressure increase converted by the momentum of the fluid is the dynamic pressure.
2.1.1.5 Total pressure
The sum of static pressure and dynamic pressure at a given location.
[GB/T 30206.1-2013, definition 2.55]
2.1.1.6 Static pressure differential
The difference in static pressure between two points in the fluid.
2.1.1.7 Total pressure differential
The difference in total pressure between two points in the fluid.
