Hollow plastic plugs (BioPortfolio, Dorset, UK) were inserted 0.25 cm into each end of a silastic tubing (inner diameter 1.57 mm, outer diameter 3.18 mm; Dow Corning, Midland, Michigan), making silastic tubing with hollow lengths of 0.65 cm, 1 cm, and 1.32 cm.
The rotating bowl of a tubular centrifuge consists of a long hollow tube (length many times its diameter) as shown schematically in Figure 1.
Analysis of variance (ANOVA) revealed that the important factors contributing to extraction efficiency are extraction time, stirring rate and hollow fiber length.
In this Paper transient thermo-elastic analysis of a thick hollow finite length cylinder made of two dimensional functionally graded materials (2D- FGMs) has been investigated.
Four design and operation variables, including feed temperature, hollow fiber length, feed volume flow rate and vacuum pressure, were optimized to minimize water production cost (WPC) using genetic algorithm (GA).
The feed temperature should be adopted as high as possible, while the hollow fiber length cannot be too long to result in a decrease in water flux and an increase in pressure drop.
The effect of different extraction conditions (i.e., type of acceptor phase, hollow fiber length, ionic strength, stirring rate, and extraction time) on the extraction efficiency of the TCAs was investigated and optimized using central composite design (CCD) as a powerful tool.
A comparison of two polysulphone hemofilters with different hollow fiber lengths showed transmembrane pressure and increased survival time being lower with the longer filter [ 34].
At the same time, using the optimized hollow fiber module length and packing density in the DCMD process, ultra pure water with a low salinity of 0.062 g/L was attained at a condition of high energy efficiency (EE).
If you cannot find the hollow, measure the length of the pregnant woman's index finger.
