Sand is not just sand to engineers or other professionals. Each application has a specification.
* Coarse sands are good for rapid filtering of flids * Silica sands are imperviu to chemicals * DEsert sands have smoother grains * Some sands are one grain size, others have a size istribution

What is stub in and stub on in piping?
For branching of one size lesser of run pipe, Stub On is preferred. For other branching less than one size of run pipe stub in is preferred. The Design is based on ANSI B 31.3
What is stronger than concrete?
steel
Which of these is a different between EFPs and other IEDs?
EFPs have a higher casualty rate than other IEDs
Do letters reach faster than a telegram?
no
What did elwood Haynes do other than inventing?
Invinting
What is coarse sand?
Coarse sand is typically bigger in diameter than fine sand. While fine sand typically consists of sand granules that measure up to a quarter of a millimeter in size, coarse sand typically measures between one half and a full millimeter in size.
What is coarse grain in metals?
Fine grains are harder than coarse grains
What are difference between sand and gravel?
Sand is more fine than gravel
Why is the void ratio of a fine grained soil greater than that of coarse grained soil?
In fine grained soil very fine particle are there which has got some chemical repulsion, these chemical repulsion does not allow particle to come closer due to which void ratio of fine grained soil is higher than coarse grained soil.
What represented coarse sand?
Sand can come in several grades. Silver sand being fine grains. Course grains being more likely found at the seaside if shell is mixed into the grains. In some area, volcanic erosion may result in a grey coloured sand, rather than the expected golden sands of our childhood expectations.Building sand may be from inland site, so as to avoid the salt content should the sand be brought from coastal sand banks.
Does sand have smaller particles than gravel?
Yes, sand has fine particals, gravel is much larger.
Does fine grained metals contain smaller unit cell than coarse grained metals?
it is granite it is granite
What is coarse aggregates?
Raw materials that are a component in concrete, aggregates are inert granular materials such as sand, gravel or crushed stone. Coarse aggregates are particles greater than 4.75mm, but they generally range between 9.5mm to 37.5mm in diameter. Primary coarse aggregates come from the land or water. Secondary aggregates are the by-products of extractive operations. The third source coarse aggregates come from is recycled aggregate, which is sand, and recycled concrete aggregate.
Why are raindrop impressions are preserved in in fine grained sedimentary rock rather than a coarse grained?
because raindrops have small particles and coarse grained sedimentary rocks have big particles so it is easier for raindrop impressions to occur in fine grained sedimentary rocks
The slope of the mold release?
The appropriate release slope can avoid the product pulling hair (pulling flowers). Smooth surface of the mold slope should be ≥ 0.5 degrees, fine grain (sand surface) surface is greater than 1 degree, coarse grain surface is greater than 1.5 degrees.
What are the disadvantages of the water frame?
Advantages:Made a strong, tough yarnQuicker than weavingDisadvantages:Made coarse yarnNot as fine of a yarn as the Spinning Jenny's
Why fineness modulus of coarse aggregates is more than that of fine aggregates?
how does the fineness modulus of aggregate affect the strength of concrete
