Helminth eggs of concern in wastewater used for irrigation have a size between 20 and 90 ?m and a relative density of 1.06 1.23.
32.
If the relative density is exactly 1 then the densities are equal; that is, equal volumes of the two substances have the same mass.
33.
The latter provides undisturbed specimens, on which testing can be conducted, for instance, to determine the soil s relative density, water content and mechanical properties.
34.
In the early years the slurry had a low relative density that led to difficult construction conditions with seepage and sloughing on the northern wall.
35.
:I'd like to see a better explanation ( other then mine ) about how relative density conveys more information then the actual density does itself.
36.
If the reference material is water then a substance with a relative density ( or specific gravity ) less than 1 will float in water.
37.
In the classical examples listed above, the target quantities were relative densities : volume fraction, surface area per unit volume, and length per unit volume.
38.
Where the relative density of the sample is close to that of water ( for example dilute ethanol solutions ) the correction is even smaller.
39.
Her contributions to technology are reputed to include the invention of the hydrometer, used to determine the relative density ( or specific gravity ) of liquids.
40.
It has generally been accepted that tectonic plates are able to move because of the relative density of oceanic lithosphere and the relative weakness of the asthenosphere.
