Gauge Pressure:
- Gauge pressure is the pressure relative to the ambient atmospheric pressure.
- It is the difference between the absolute pressure and the atmospheric pressure.
- Gauge pressure can be positive or negative depending on whether it is above or below atmospheric pressure.
Vacuum Pressure:
- Vacuum pressure is the pressure below atmospheric pressure.
- It is often measured in terms of the difference from atmospheric pressure.
Local Atmospheric Pressure:
- Local atmospheric pressure is the pressure exerted by the atmosphere at a specific location.
- It varies with altitude and weather conditions.
System Pressure:
- System pressure is the pressure within a specific system, such as a hydraulic or pneumatic system.
