volume percent

Volume percent is a common expression of a solution's concentration.

The new work, using carefully controlled conditions has raised that lower limit to about 15 volume percent.

It is expressed in units of volume percent of oxygen.

Older estimates of the minimum amount of oxygen needed were about 12 volume percent.

For alcoholic beverages, see alcohol by volume and Volume percent.

Replies: The atmosphere is composed roughly of 20% oxygen and 80% nitrogen (volume percent).

One iron meteorite, Mundrabilla contains 25 to 35 volume percent troilite.

Volume percent is usually used when the solution is made by mixing two fluids, such as liquids or gases.

As an example, a wet basis concentration of 40 ppmv in a gas having 10 volume percent water vapor would have a:

Alcoholometers have scales marked with volume percents of "potential alcohol", based on a pre-calculated specific gravity.

Results show a 20% enhancement in thermal conductivity over base fluid (Therminol66) at 2 volume percent (vol%) of copper nanoparticles.

The size and/or volume distribution of drops in a spray is typically expressed by the size versus the cumulative volume percent.

Replies: Remember that air is already 80 volume percent nitrogen, so the leak rate between air and pure nitrogen is not very different.

Paraffin content (volume percent)

Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen).

These fine- to medium-grained rocks have a rather dark appearance, they are quite rich in green hornblende but nearly devoid in alkali feldspar (less than 10 volume percent).

Particulate matter (PM) in the atmospheric air or in any other gas cannot be expressed in terms of ppmv, ppbv, volume percent or mole percent.

Boot has open porosity of greater than 50 (or 80) volume percent and can consist essentially of zirconia, such as a sintered mass of zirconia fibers."

The maximal authorized yield for Bordeaux AOC is 55 hectoliter per hectare, and the alcohol level of the wine must be between 10 and 13 volume percent.

Since ambient air contains about 79 volume percent gaseous nitrogen (N), which is essentially non-combustible, the largest part of the flue gas from most fossil-fuel combustion is uncombusted nitrogen.

It averages 35.9 volume percent in the Western Transvaal while the Atok Platinum mine in Bushveld boasts 60 volume percent.

The natural rock formations in the area have been shedding asbestos-rich debris into stream valleys for millions of years The average New Idria rock contains 5-15% volume percent short fiber asbestos.

To convert from volume percent ozone in air to weight percent, you need to know that the molecular weight of ozone is 48 and the average molecular weight of air is about 28.

PONA, PIONA or PIANO analysis, measured by detailed capillary gas chromatography (usually in volume percent but can also be in weight percent):

Although ppmv and grains per dscf have been used in the above examples, concentrations such as ppbv (i.e., parts per billion by volume), volume percent, grams per dscm and many others may also be used.
