What is the volume of voids or open space in a rock or unconsolidated material?
The volume of voids or open space in a rock or unconsolidated material is called porosity. It is a measure of the amount of empty space within the material. Porosity is expressed as a percentage and can vary based on factors such as grain size, sorting, and cementation.
What is BCM in coal mining term?
BCM in coal mining stands for Bank Cubic Meters. It is a unit of measurement used to quantify the volume of material excavated or extracted in its natural state from a coal deposit. This measurement excludes any voids or gaps between the material, providing an accurate representation of the actual volume mined.
When A dry soil sample has a volume of 500 mL After 400 mL of water are added to the soil the soil becomes saturated with 150 mL of surface water left on top What is the porosity of the soil?
Porosity is calculated by dividing the volume of voids (pores) by the total volume. In this case, the volume of voids is the difference between the volume of water added and the volume left on top of the saturated soil (400 mL - 150 mL = 250 mL). The total volume is the sum of the dry soil volume and the water added (500 mL + 400 mL = 900 mL). Therefore, the porosity of the soil is 250 mL / 900 mL, which is approximately 0.28 or 28%.
What is formed by the erosion of a soft rock formations by flowing groundwater?
Caves and caverns are often formed by the erosion of soft rock formations by flowing groundwater. Over time, the water dissolves and carries away the rock material, creating underground voids and passages.
How is the vesicular texture of an igneous rock formed?
A vesicular texture is one where there are small voids within the igneous rock. These tend to form in extrusive igneous rocks due to the loss of confining pressure which causes gasses dissolved in the molten material to come out of solution or exsolve. These gasses form bubbles within the cooling lava and can become trapped if the lava cools rapidly, leaving a permanent gas bubble or void space within the solidified igneous rock.
What is the volume of voids or open space in a rock or unconsolidated material?
The volume of voids or open space in a rock or unconsolidated material is called porosity. It is a measure of the amount of empty space within the material. Porosity is expressed as a percentage and can vary based on factors such as grain size, sorting, and cementation.
Is the volume of voids or open space in a rock or unconsolidated material?
the gradual removal of bed rock is what it comes form these are big sink holes
What term denotes the percentage of open space or voids in a material?
Porosity
When is the particle density equal to the bulk density?
The particle density is equal to the bulk density when there is no pore space or voids between the particles. This means that the bulk density (mass of the material per unit volume including both solid material and voids) will be the same as the particle density (mass of the particles per unit volume excluding any void spaces).
What is the formula for void ratio?
Void ratio (e) is typically defined as the ratio of the volume of voids to the volume of solids in a soil sample. The formula for void ratio is e = Vv/Vs, where Vv is the volume of voids and Vs is the volume of solids in the soil sample.
What will be the voids in stone masonry?
A void is a space or cavity,
What is void in amorphous material?
In amorphous materials, voids refer to spaces or gaps within the material where there is no solid substance present. These voids can affect the material's properties like strength and density, and can also impact its thermal and electrical conductivity. Understanding and controlling voids is important in the processing and performance of amorphous materials.
What is the difference between voidage and porosity?
"Porosity" can be used to refer to voidage of a granular material. Pporosity could also denote the relative volume of pores, cracks and spaces in the solid body, while voidage deals exclusively with the amount of spaces between particles in relation to the overall volume occupied by the granular material. Porosity is measure of void spaces in a material.voidage means the relative amount of space between materials that are tightly packed ..........
What is the difference between Apparent Density Density?
In metallurgy it is the weight per unit volume of a metal powder, in contrast to the weight per unit volume of the individual particles.In architecture the apparent density is1. The mass per unit volume of in-place thermal insulation.2. The mass per unit volume (or the weight per unit volume) of a material, including the voids which are inherent in the material.
What is perosity?
Porosity is a measure of the open spaces (pores) in a material, typically a rock or soil. It is expressed as a percentage of the volume of these voids out of the total volume of the material. Porosity is important in geology and hydrology as it affects the storage and movement of fluids such as water and oil in subsurface formations.
What is apparent relative density?
Apparent relative density is a measure of the density of a material compared to the density of another reference material, typically water. It is calculated by dividing the apparent mass of the material by the mass of an equal volume of the reference material. Apparent relative density does not take into account the presence of any voids or pores in the material.
What are the differences between solid density and bulk density?
Solid density is just that - the weight of a fixed volume of the solid material. But if the material is not solid, that is, if it is divided into particles or grains, or "chunks" or the like, then they will not "pack down" and be as dense as a solid volume of the material. Let's try an example. If we have a shoe box full of glass marbles, it will have a given weight. And, if we have the dimensions of the box, we can take the weight and the volume of the box and make a density calculation. But the box won't actually be "solid glass" as it would if we could ignore the "packing" of the spheres. The marbles end up leaving space between and around them when we put them in the box. They're round, and they can't take up all the space in the box. They simply can't. Because they can't take up all the volume in the box, it gives rise to what we call bulk density. If we take the the density of the glass from which the marbles are made, we could find the weight of a volume of that glass that was equal to the volume of the shoe box. The weight of the glass in a shoe box that is "solid glass" will be higher than that of the weight of the marbles in a full box. And that's because it is based on our filling the box with marbles and not being able to make the spaces between the marbles disappear. Got links if you want 'em.
