The 200-400 mesh size is best for DNA extraction. The smaller sizes are usually used for metal ion extraction.
177 micron
Assuming the temperature stays constant and there is no leakage of gas, then if the container decreases in size then the pressure will increase.
No. Electronegativity decreases as the size of the atom increase. As you go across a row in the periodic table, you will see that electronegativity increases and the size of the atom decreases. Similarly, as you go down a column you will notice that the size of the atom increases and electronegativity decreases.
atomic size decreases across a period
Random error and sample size have an inverse relationship...As sample size INCREASES random error DECREASES. There's a good explanation at the related link.
No. of openings per square inch of wire mesh is specifies the mesh size and its again depends on wire dia also. If the number of openings per square inch is more then partical size which it can pass through the filter will be less. For example for 325 mesh size, where in 44 micron size of particle can get filter. In 200 mesh size 74 micron size of particle will get filter.
The mesh size in the earthing design for substation can be various size depend on the area. For area that does not contain equipment, we could increase the mesh size because there is no equipment to cause touch potential. But if the area is at the corner of the substation, the mesh size should be smaller because to limit the step potential.
.044mm
mesh 500 micron=31 inches=0.0012
That would depend on the wire thickness, and size of mesh.
Standard error (which is the standard deviation of the distribution of sample means), defined as σ/√n, n being the sample size, decreases as the sample size n increases. And vice-versa, as the sample size gets smaller, standard error goes up. The law of large numbers applies here, the larger the sample is, the better it will reflect that particular population.
Mesh size is usually used in the US. It's just an alternative system used to describe the hole size. For example, 35 mesh (US) is the same as 0.5mm or 500 microns.
Mesh denotes particle size or granulation of powder. When guar gum powder is prepared, it is granulated through mesh screens during the sieving process. +40 mesh means powder will pass through a sieve of 40 mesh. -100 mesh means powder will not pass through a sieve of 100 mesh. +40/-100 mesh guar gum powder means 90% of powder will pass through 40mesh but not through 100 mesh. Hence particle size lies between 40mesh and 100mesh. Read wikipedia article on mesh.
Microcrystalline cellulose is commercially available in different particle sizes and moisture grades which have different properties and applications.Avicel PH 101Has a nominal mean particle size of 50 microns
80 mesh size, 44,000 spics, make a Oz. 40 mesh size, 22,000 " " ". piece`s 1/8 inch. in size 200 for a oz. Do the math......And in the back ache.
