The mass of a moist soil sample having a volume of 0.0057 m3 is 10.5 kg. The moisture content and the specific gravity of soil solids were determined to be l 3 % and 2.68, respectively. Determine the dry density (kg/m'), porosity, and void ratio of the sample Determine and void ratio of the

### Reconstruction of 3D Porous Media From 2D Slices

Porosity is a measure of the void spaces in the material and is a fraction of the volume of voids over the total volume. It takes values between 0 and 1. The porosity comparison is provided in Fig.4and shows close agreement. To analyse pores properties, we computed two-point correlations (TPC16). We used PoresPy library17 code. For two

### PAPER OPEN ACCESS Related content Causes and remedies for ...

2. Porosity . Porosity is defined as the volume fraction of (small) voids in a material. In a composite, a void is space that is not occupied with resin or fibre. When individual voids get large, they are no longer treated a at continuum level but as discrete objects with a …

### Porosity and Permeability and Infilration

Porosity, Permeability and Infiltration Permeability – the rate at which a fluid flows through a porous substance under given conditions. Porosity (void space) – the portion of a volume of material that is not solid Infiltration – movement of a fluid into the surface of a porous substance. Infiltration and Permeability are used interchangeably in reference materials

### Dependency of Tortuosity and Permeability of …

The approach uses a volume averaging method through which the macroscopic tortuosity tensor is related to both the average porosity and the directional distribution of pore spaces. The permeability tensor is derived from the macroscopic momentum balance equation of fluid in a porous medium and expressed as a function of the tortuosity tensor and the internal structure of the material.

### Sand / Media Specifications

media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging.
