On this plot, temperature glide is the horizontal distance (meaning at fixed pressure) between the bubble point and dew-point lines of the zeotropic blends.
Therefore, lowering the surface tension of a liquid applied over a microporous membrane (or any porous material) induces a condition whereby less pressure is required to break the air water interface and therefore Bubble Point Pressure is decreased.
Bubble point is the minimum pressure at which a wetted membrane allows a constant stream of air bubbles through it.
If there is a transition from bubble point to dew point saturation conditions over the calculation interval, the GOC depth will be estimated.
2-6) EU Annex 1, paragraph 113, however, states: "The integrity of the sterilized filter should be verified before use and should be confirmed immediately after use by an appropriate method such as bubble point, diffusive flow or pressure hold test.
Undersaturated oil viscosity correlations, which usually use saturated crude oil viscosity and pressure above the bubble point to predict viscosity of undersaturated oil reservoirs.
Those who believe there is a bubble point out that such buyers likely won't have savings to bail them out; the Commerce Department's Bureau of Economic Analysis reported in recent weeks that the net average savings for Americans has hit zero.
The Clamp-On Porometer measures the bubble point, mean flow pore diameter, pore size distribution, gas permeability, and envelope surface area, but does not require a sample to be cut out from the bulk material.
In this way, bubble point measurements on a sample of fixed composition were obtained.
Bubble point determinations are made by performing a series of pressure hold tests at incrementally higher test pressures and monitoring for a rapid increase in pressure decay indicating a high amount of bulk gas flow through the filter's membrane.
TO MEET CAPILLARY FILTRATION REQUIREMENTS WITH OVERPRESSURE, OUTOKUMPU HAS DEVELOPED A NEW CERAMEC[R] FILTER MEDIA WITH A HIGHER BUBBLE POINT PRESSURE.
At the other extreme, when an all-liquid mixture is gradually heated, the bubble point curve shows the temperature at which vaporization (boiling) will start.
