For less dened shapes, volume can be determined by water displacement. Volumes of liquids such as water can be readily measured in a graduated cylinder. To use the water displacement method, an object (in this case, a small metal cylinder) is inserted into a graduated cylinder partially lled with water. Water displacement test method is used to determine the dry density of soil. It is suitable for evaluating in-place dry density of cohesive soil due to the nature of specimen required. The soil sample should be trimmed to obtain a regular shape and then coated it to make it impervious to water. In these instances, the true density can be measured by using a gas as the displaced fluid if the material does not contain closed pores, which cannot be penetrated by the analysis gas. Therefore, the density experimentally determined by gas pycnometry generally is the so called skeleton density of the material which equals the true solid state density only for samples without closed pores.

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F).

The water content should be reported to the nearest 0.1% stating whether this corresponds to in situ water content, in which case precautions taken to retain water during sampling and storage should be specified. 2.

This is because different metals have different densities.Also 0bjects, put in water, will displace water. The displaced water will be equal to their volumes. A metal or alloy that is less dense will displace more water than a denser one. This will be the density of the material your object is made of.

Jan 31, 2006 · Density is calculated by and specific gravity by the same equation and dividing both sides by the density of water with reference to temperature. Essentially the same process can be used to determine the volume of an unknown, enclosed space. First the object containing the void is weighed empty.

Put an object into the water you will see how the level of water in the cylinder has moved up (to 23 ml, for example). The volume of displacement is how much the water level has changed (in this case, it is 0.3 ml). The volume of the object is equal to this amount because it is the amount of space that it took up while in the water.
