differential pressure

differential pressure

[‚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.

differential pressure

The pressure difference between two systems or volumes. Normally, it refers to cabin pressurization, and the gauge shows the differential pressure in addition to the cabin altitude. Once the differential pressure exceeds a specified figure, the spill valve opens and brings the differential pressure within limits.

The non-decoupled approach can be modified where differential pressure at the building connection will not be adequate during all of the year by adding a building pump that is installed with a parallel bypass and check valve so the pump is only operated when it is required to increase differential pressure for the building as shown in Figure 3.
