WebUniversity of Luxembourg WebSep 25, 2024 · The image above represents porosity. To compute for porosity, two essential parameters are needed and these parameters are Volume of void (Vv) and Volume of the soil (V). The formula for calculating porosity: n = Vv / V Where: n = Porosity Vv = Volume of Void V = Volume of the Soil Let's solve an example; Find the porosity when the

WebThe hydraulic gradient is the driving force that causes groundwater to move in the direction of maximum decreasing total head. It is generally expressed in consistent units, such as feet per foot. For example, if the difference in water level in two wells 1000 feet apart is 2 feet, the gradient is 2/1000 or 0.002 ( Fig. 3-12 ). WebBoussinesq's Formula Equation.

WebThe Specific Gravity of Soil is defined as the ratio of the weight of a given volume of the material to the weight of an equal volume of distilled water. It is an important parameter in soil mechanics for the calculation of the weight-volume relationship. Gs = Unit weight (or density) of soil sample only / Unit weight (or density) or water. WebApr 24, 2024 · G s = specific gravity (the ratio of the density of the soil to the density of water), no units; I D = density index (relative density), percentage (%) n = porosity (ratio of …
WebSoil is composed of solids, liquids, and gases. Liquids and gases are mostly water and air, respectively. These two (water and air) are called voids which occupy between soil particles. The figure shown below is an idealized soil drawn into phases of solids, water, and air. Weight-Volume Relationship from the Phase Diagram of Soil. WebMohr’s Circle Equation •The circle with that equation is called a Mohr’s Circle, named after the German Civil Engineer Otto Mohr. He also developed the graphical technique for drawing the circle in 1882. • The graphical method is a simple & clear approach to an otherwise complicated analysis.
