Study Notes
Pressure Definition
- Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Units of Pressure
- The SI unit of pressure is the pascal (Pa), which is one newton per square metre (N/m2).
- The traditional unit of pressure in the imperial and US customary systems is the pound-force per square inch (psi, symbol lbf/in2).
- The atmosphere (atm) is a unit of pressure, with the torr being defined as 1⁄760 of this.
- Manometric units, such as the centimetre of water, millimetre of mercury, and inch of mercury, express pressures in terms of the height of a column of a particular fluid in a manometer.
Gauge Pressure
- Gauge pressure is the pressure relative to the ambient pressure.
