The change in pressure or the pressure drop across a component or device located within the airstream; the difference between static pressure measured at the inlet and outlet of a component device.
The rate at which pressure is changing down the well. (psi/ft or bar/m).
The pressure difference between two points in a system. For example, the difference in pressure between the upstream and downstream taps of an orifice plate, used to measure volume passing through the orifice.
1. The difference in pressure between two points of measurement. 2. The static pressure difference generated by the primary device when there is no difference in elevation between the upstream and downstream pressure taps.
The difference between two pressures. Differential Pressure Flow Meters use differential pressure to compute volumetric flow rates.
The difference betweeen a reference pressure and a variable pressure.
the difference between the measurements of pressure at two points in a system
The difference in pressure between two points of a system, such as between two sides of an orifice
The measured difference between two separate but related pressures.
It is the difference in pressure between two points in a vacuum or filter system. In filter assemblies, it is usually expressed as the delta P between a housing inlet and outlet.
The difference in pressure between two points of measurement for example, the difference in the pressure on both sides of an orifice installed in a pipe through which fluid flows.
In a Dust Collection System usually refers to the difference in pressure (typically measured in inches of water column W.G.) between the dirty side of the baghouse and the clean side of the baghouse. Essentially this yields the pressure drop or resistance to the air-flow through the filter bag.
The Static Pressure difference between the upstream inside pipe diameter and the throat diameter resulting from the reduced area of the cross section.
The difference between suction pressure and discharge pressure of a pump; increment of pressure added by each pump operating in series in pumping stations; pressure drop or loss between inlet and outlet of a filter, meter, or other accessory offering resistance to flow.
The difference in pressure between any two points of a system or component. ( 070)
Difference in pressure between two given points of a filter, filter separator etc.
The difference in pressure between the upstream and downstream sides of a filter. Difference in pressure between two points in a system. In filters, this is usually measured between the inlet and outlet of the filter housing, and is a determining factor of filter service life.
The difference between the pressure in a well due to the mud column and the pressure in the surrounding rock at any point. See also Sticking.
The difference in pressure between two points in a fluid system usually in filtration systems expressed as P between a housing inlet and outlet.
The difference in pressure (psi or kPa) between the suction pressure and discharge pressure.
The difference in static pressure between two identical pressure taps at the same elevation located in two different locations in a primary device.
The difference between pressures measured at two points or levels in a system.
(1) The difference in pressure between two given points. (2) The combined pressure caused by the debris, filter cake, precoat and septum, expressed as ("delta P"). (3) The effluent pressure minus the influent pressure.
The difference between the actual measured pressure and a fixed reference point.
The difference between two fluid pressures. For example, the difference between the pressure in a reservoir and in a wellbore drilled into the reservoir.
The difference in pressures at two points in a water system. Differences may be due to variations in elevation, or to friction losses, or to pressure drops caused by resistance to water flow through pipes, softeners, filters, or other devices.
See pressure differential.
Pressure difference in two parts of a system or two areas.
