If the density of a substance is known, to calculate the specific gravity of a substance simply divide the density of the substance by the density of water or air. Because the density of water is 1000 kg/m3or 1g/cm3, it is simple to calculate. The density of air is 1.205 kg/m3. Me...
Learn about specific gravity, its relation to density, and how to convert one unit to the other. See which instruments are used to measure specific gravity.
Specific volume is a term, usually applied to gases, that indicates the amount of volume occupied by a certain mass of the gas. Specific volume is an intensive property, which means that it is not determined by the total amount of gas. It can vary according to other factors such as press...
Specific gravity, called Relative Density, is a measurement used to define the weight or Density of a substance compared to the Density of an equal volume reference material at a specified temperature. In most cases, the reference material is liquid water or gaseous air. The specific gravity rep...
Weight density is the ratio of the amount of weight a body has to the volume.density = weight / volume Definition of specific gravitySpecific gravity is the ratio of the density of a material to the density of water.weight density = density of a material / density of water ...
If you plop an egg in water, the egg will sink. The reason is that the egg has a specific gravity and density that is greater than water. However, something magical happens when you pour salt into the water. Suddenly the egg begins to float. ...
The volume occupied by a unit mass of a substance is known as its specific volume. It is calculated by dividing the volume (V) by the mass (m) of the substance. It is a useful property for understanding the density and compressibility of a substance....
Optical density can be used in OHS contexts to determine how well protective lenses will protect the user from exposure to a specific light source. As absorbance measures the attenuation of light through a material, OD numbers are an effective way to consider the amount of exposure that a given...
It should be noted that such tests do not give an actual density, as density is measured in mass per volume; these tests merely measure the amount of specific substances in a given area of bone. The strength of one's bones is closely related to his bone density. Those with low bone ...
The measure of the rate of absorption, by which this RF energy is absorbed by our body while using a wireless device is called Specific Absorption Rate (SAR). The unit of SAR is Watts per Kilogram (W/Kg). In our day-to-day life, we are constantly surrounded by different types of ...
