Want to know what’s the difference between these three terms? Here below I am providing a basic difference between Pressure, Absolute Pressure, and Vaccum Pressure in a detailed manner.
It is defined as the ratio of Force acting per unit Area of the cross-section.
SI Unit of Pressure is Here
Measurement of pressure is done by the manometer.
The Sum of Atmospheric pressure and Gauge pressure is called Absolute Pressure. or
The Difference between Atmospheric pressure and Vaccum pressure is also called as Absolute Pressure
|Absolute Pressure=Atmospheric pressure+Gauge pressure|
Absolute Pressure=Atmospheric pressure-Vaccum Pressure.
It is defined as the difference between Atmospheric Pressure and the Absolute Pressure
|Vaccum Pressure = Atmospheric Pressure-Absolute Pressure.|
