Sediment transport - Wikipedia

Sediment transport is the movement of solid particles , typically due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained. Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay; the fluid is air, water

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

Sieve - Wikipedia

US standard test sieve series. A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering or sedimentology) to assess the particle size distribution (also called gradation) of a granular material. Sieve sizes used in combinations of four to eight sieves.

Sieve | Definition of Sieve at Dictionary.com

Sieve definition, an instrument with a meshed or perforated bottom, used for separating coarse from fine parts of loose matter, for straining liquids, etc., especially one with a circular frame and fine meshes or perforations. See more.

Molecular sieve - Wikipedia

A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.As a mixture of molecules migrate through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of highest molecular weight

Chapter 13 - SEDIMENT MEASUREMENTS

The fraction remaining on each sieve is weighed and its weight expressed as a percentage of the weight of the original sample. The cumulative percentage of material retained on the sieves is calculated and the results are plotted against the representative mesh sizes of the sieves. A series of eight sieves can be used for sediment

What is a Sand Sieve? (with pictures)

Sand sieves of gradually decreasing size from top to bottom are arranged in a column, sometimes held by a frame or other apparatus. The sediment sample is weighed and poured into the top sieve, and this sieve is shaken for a set amount of time. As the sediment passes through the sieves, they are each shaken for the same amount of time.

Rare earth metals found on Pacific's muddy floor - CBS News

Researchers have found high concentrations of rare earth metals, essential materials for making nearly all high-tech electronics, in mud on the floor of the Pacific Ocean, according to study

French Press vs Pour-Over Coffee: What Is the Difference

On the flip side, the filters that most pour-over brewers call for are great at holding back sediment and even coffee oils, which means the resulting drink is usually noticeably lighter or silkier on the tongue—think of it more like a sheet than a blanket.

Why did my homemade lobster stock smell so foul? Help

I strained it a few times through a sieve lined with cheesecloth, poured it into a plastic container and put it in the fridge. A day or two later, when I looked in the fridge, I noticed that it had a lot of sediment at the bottom, similar in proportion and appearance to the sediment that forms at the bottom of a carboy of fermenting wort when I

Sieve Analysis, Particle Size Analysis

Particle Size Passing the Sieves: In Sieve analysis the notation Dxx refers to the size D, in mm, for which xx percent of the sample by weight passes a sieve mesh with an opening equal to D.The D10 size, sometimes called the effective grain size, is the grain diameter for which 10% of the sample (by weight) is finer.

Sieving methods of sieve analysis - Retsch

Tap sieve shakers are specified in various standards for particle size analysis. The number of comparisons between particles and sieve apertures is substantially lower in tap sieve shakers than in vibratory sieve shakers (2.5 s-1 as compared to ~50 s-1) which results in longer sieving times.
