|
Atmosphere pressure |
the pressure exerted by the atmosphere at the earth's surface. Pressure caused by the weight of the air. |
|
|
Gauge pressure |
pressure difference between a system and the surrounding atmosphere. pg = ps – patm |
|
|
Vacuum |
pressure below atmospheric pressure are called vacuum pressures and are measured by vacuum gages that indicate the difference between the atmospheric pressure and the absolute pressure. |
|
|
Absolute pressure |
Sum of the gauge pressure and atmospheric (barometric) pressure |
|
|
Partial pressure |
Pressure exerted by one gas in a mixer of gases |
|
|
Pressure |
force exerted on a surface per unit area. |
|
|
