It is often desirable to meter multiphase fluid flow in pipes (e.g. bore holes). In order to obtain reliable/accurate flow rate measurements it is known to incorporate obstructions in the flow path to cause homogenisation. A non-obstructive method of homogenising the flow of a multi- phase mixture of fluids in a bore hole comprises providing in the bore hole a pipe section which has an ...

parameters onthe homogenising effect. The theory of globule disruption by turbulent eddies ("micro whirls") is based on the fact that a lot of small eddies are created in a liquid travelling at a high velocity. Higher velocity gives smaller eddies. If an eddy hits an oil droplet of its own size, the droplet will break up. This theory predicts how . the homogenising effect varies with the ...

01.09.2010· The index calculation is a type-specific multimetric system based on five equally weighted metrics, which are taxa richness, number of Ephemeroptera, Plecoptera and Trichoptera taxa, number of other sensitive taxa, the Shannon–Wiener diversity index and the mean tolerance score. The final index value is expressed as an Ecological Quality Ratio ranging from zero for very bad ecological ...

Precipitation is another factor that might influence the results. Heavy precipitation as rainfall might lead to increased run-offs from land and overflow water from the sewage network, which may increase the bacterial numbers in the water: the questionnaire reveals that 100% of the participants agreed with this statement, but 42% thought that precipitation also could reduce the bacterial ...

The disintegration of the original fat globules is achieved by a combination of contributing factors such as turbulence and cavitation. The homogenization reduces fat globule size from an average of 3.5 µm in diameter to below 1 µm. This is accompanied by a four- to six-fold increase in the fat/plasma interfacial surface area. The newly created fat globules are no longer completely covered ...

Definition. Homogenization (from "homogeneous;" Greek, homogenes: homos, same + genos, kind) is the process of converting two immiscible liquids (i.e. liquids that are not soluble, in all proportions, one in another) into an emulsion (Mixture of two or more liquids that are generally immiscible).Sometimes two types of homogenization are distinguished: primary homogenization, when the emulsion ...

19.10.2020· I remember discovering this formula by accident when I was a junior in high school. I was messing around on my Ti-83, when I discovered that `e^(i*pi)` resulted in `-1`. That blew my mind, so I showed my pre-calc teacher and he thought it was just a calculator glitch because it didn't know how to calculate imaginary powers.
