Study Notes
Units of Pressure
- 1 bar is equivalent to 105 Pa, 102 kPa, and 0.1 MPa
- 1 atm (atmospheric pressure) is equivalent to 1.01325 bar, 14.696 psia, and 760 mmHg
Pressure Measurement
- Pressure is measured relative to absolute zero pressure in all calculations of state
- Pressure can be measured relative to atmospheric pressure, which is called gauge or vacuum pressure
Definition of Pressure
- Pressure is defined as force per unit area
- The unit of pressure is the Pascal (Pa) in the SI system, which is equivalent to N/m2
- In the English system, the unit of pressure is psia (pound-force per square inch absolute) or lbf/in2
