Study Notes
Compressed Air System
Pressure
- Defined as the force exerted per unit area
- Measured in units of force per unit area (e.g. pounds per square inch, pascals)
- In a compressed air system, pressure is created by the compressor and stored in the receiver tank
Gauge Pressure
- The pressure measured relative to atmospheric pressure
- Gauge pressure is the difference between the absolute pressure and atmospheric pressure
- Measured using a gauge, which shows the pressure above atmospheric pressure (e.g. 100 psi gauge is 100 psi above atmospheric pressure)
- Importance:
- Affects the performance of pneumatic tools and equipment
- Impacts the efficiency and safety of the compressed air system
