The drainage density is an inverse function of permeability. The less permeable a rock is, the less the infiltration of rainfall, which conversely tends to be concentrated in surface runoff. Drainage density of the study area is calculated using line density analysis tool in ArcGIS software. The study area has been grouped into five classes.

rocks comprising the crust of the Earth have a density between 2.6 and 2.7. The effect of density on porosity follows a mixing law. The porosity,, is the fractional pore volume of a rock. The total mass of a volume of rock V T is made up of the mass of the pore fluid, of density f, plus the mass of the matrix minerals of density ma

From this Table, it can be seen that the entire range of densities covers a factor of about eight from 1.0 g/cm3 for water to 8.1 g/cm3 for cinnabar. There is considerable overlap between rock types, although in general, sediments ...

* Note that even if pounds per cubic foot is often used as a measure of density in the U.S., pounds are really a measure of force, not mass. Slugs are the correct measure of mass. You can divide pounds per cubic foot by 32.2 for a rough value in slugs.

Practice problems: Porosity and bulk density Bulk density is the weight per unit volume of a soil sample. 1. Calculate the bulk density of a 400 cm3 soil sample that weighs 575 g (oven dry weight). r b = M s /V s = 575g/400cm 3 = 1.44g/ cm 3 . 2. Calculate the bulk density of a 400 cm3 soil sample that weighs 600 g and that is 10% moisture.

Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.

Density is a basic property of a material that is equal to the objects mass divided by its volume. However the determination of an accurate density for some rock materials can difficult. This difficulty comes from many sources such as irregular volume, porosity, moisture content of the material, permeability of the material and the lack of a clear definition of density itself.

Another tricky thing about density is that you can't add densities. If I have a rock that is made up of two minerals, one with a density of 2.8 g/cm 3, and one with a density of 3.5 g/cm 3, the rock will have a density between 3.5 and 2.8 g/cm 3, not a density of 6.3 g/cm 3.This is because both the mass and the volume of the two minerals will be added, and so when they are divided to get the ...
