Differential pressure is essentially the difference in pressure between two given points. It is a type of pressure measured within different industries using differential pressure sensors. Gauge pressure refers to the difference between a measured point and the atmosphere.

What is differential pressure formula?

Firstly, differential pressure (DP or ∆P) is the difference between any two applied pressures. ... Differential pressure is calculated by subtracting one of these values from the other. If Pipe A flows at 100 psi and Pipe B flows at 30 psi, the differential pressure would be 70 psi.

What is differential pressure in physics?

[‚dif·ə′ren·chəl ′presh·ər] (physics) The difference in pressure between two points of a system, such as between the well bottom and wellhead or between the two sides of an orifice.
