What pore size is related with porosity 2 of sintered glass filter?
The pore size is the average 100 micrometers.
What is sintered glass and its porosity?
Sintered glass is a glass mesh used for filtration. It can be used instead of filter paper, and in fact is preferable to filter paper. Its other advantage is that it is permanent so you can get various different pieces of glassware with sintered glass in it e.g. an enclosed filter suitable for filtration under nitrogen. As for the porosity.... Porosity of sintered glass is labelled by integers from 0-5 (viz. 0, 1, 2, 3, 4, 5) where 0 has a pore size of 160-250 micrometres and is considered course filtration, that is fluid will pass through it quickly and some finer solids will pass through. Whereas, porosity 5 has a pore size of 4-10 micrometers so even ultrafine solids will not pass through and liquids will drop through. I hope this is clear, makes sense and is helpful.
What generally happens to the porosity of sediments as they are turned into rock?
Due to the processes of compaction and cementation the pore spaces are generally reduced in size or in-filled with other minerals. This acts to reduce the porosity.
What factors affect porosity?
The larger the particle size, the higher the porosity. Also keep in mind that angular particles have a higher porosity than round particles. *Good way to remember porosity is that the spaces between particles are "pore-like."
What is the volume of open pore spaces in a rock?
This is known as porosity.
Is a glass an example of porosity?
yes.... it is an answer for porosity....
What are the spaces between rocks and soil called?
Porosity or pore space
This term refers to the percentage of soil or rock that consists of pore space?
porosity
What factors control the porosity of an aquifer?
size of the particles in the material shapes and uniformity of the material amount of cementing agent in the pore space of the material All of the above are correct.
The percentage of a rock's total volume taken up by pore space is called the?
Porosity
The percentage of a rock that is occupied by pore spaces?
Porosity, i just finished the work sheet.
What is porosity in relation to groundwater?
Porosity is a measurement of the ratio of pore space to solids in a given volume of material. The pore spaces form in soils and rocks due to the gaps between the individual clasts or grains that aggregate to form them. Compaction and consolidation (where the soil or rock is compressed) can force the grains closer together and so reduce the size of the pore spaces and so decrease the porosity. Below the phreatic surface or water table, these pore spaces are normally filled with water (there are exceptions however for simplicities sake it is a reasonable assumption). The larger the porosity of a rock or soil, the more space per unit volume there is to store groundwater. Also the larger the interconnections between the pore spaces and the greater the number of interconnections, the more permeable the material will be to the movement of groundwater. Porosity is a dimensionless quantity which is calculated by dividing the volume of void space by the total volume of the material in question. There are a number of methods of determining the value of the porosity of a material and for more information please see the related link.
