Study Notes
Pressure Units
- In the SI system, pressure is expressed in pascals (Pa).
- Gauge pressure is the pressure relative to atmospheric pressure, measured in units of pascals (Pa) or pounds per square inch (psi).
- The torr is a unit of pressure, equivalent to 1/760 of a standard atmosphere, primarily used to measure pressure in vacuum systems.
Imperial and US Customary Systems
- In the imperial and US customary systems, pressure is expressed in pounds per square inch (psi).
Manometric Units
- Manometric units, such as inches of water (inH2O) or millimeters of mercury (mmHg), are used to measure pressure in industrial and technical applications, particularly in the context of fluid flow and pressure measurement.
