What is a Pressure Differential? - Definition from ...

Aug 20, 2020 Pressure differential is the pressure difference that exists between points. This is highly relevant for day-to-day pressure measurement, especially in industry. It also describes the fluid force that exists per each unit and is measured in pounds per square inch (PSI). It is equivalent to the unit that is subtracted from a greater force per unit.
