Compacting factor test

RO performance of the CTA hollow fiber membrane used in Hollosep was measured under higher pressure and analysed in terms of A and D j j/K value. These values remained almost unchanged under operating pressure of up to 100 Kg/cm G. Moreover, long term performance test of the module at high pressure of 75 Kg/ cm2G was satisfactorily carried out with compaction factor less than 0.03. 

The ease with which concrete can be deformed by an applied stress is known as the workability of the concrete and is measured by standard tests such as compacting factor, VeBe or slump under arbitrarily chosen conditions of sample...

Prismoidal specimens of 70 x 70 x 280 mm were formed in the laboratory. The vibration time was chosen to ensure maximum compaction factor for each mix. If this was less than 0.05%, the specimen was rejected. The samples were cured at air moisture of 95-98% and temperature of 18-22 C. for 28 days, then isolated from environmental water exchange prior to testing at 1-year age. Such conditions ensured a degree of consistency of mechanical properties for all samples tested. 

The outcome of dissolution tests on pharmaceutical formulations can be influenced by a nnmber of factors including the nature of the excipients and lubricants, blending method and granulation procedure used. When the solubility of the API is not the limiting factor, the compaction pressure used to produce tablets is inversely proportional to their dissolution rate and, as noted in the previous section, directly proportional to the slope of the NIR spectra for intact tablets. Blanco et have developed various approaches for... 

J. Eadie reported in Ref 71 that the shock sensitivity of HMX/wax compacts is found to decrease as the amount of the HMX surface coated with wax increased. This thus indicates that the shock sensitivity depends on the surface area of the reactive expl exposed to reaction products. Similar results were observed 20 years earlier and reported in Ref 26. The following is a quote from this Ref, It was noted in the course of this work that the quantity of inert material per se was not the important factor in the phenomenon of desensitization. As a matter of fact, it was the thoroughness with which the explosive crystals (PETN) were coated that appeared to be an important factor in desensitization. Table 6 contains the results of the impact sensitivity tests conducted on PETN-wax mixts where both the quantity of wax in the mix and the degree of coating on the expl crystal are taken into account... 

The principal structural factor to be considered in hardness testing of multicomponent materials is the degree of consolidation of the material under test, in other words, the compactness of its structure (Colwell et al.,...

Table 18-7 has the typical design sizing criteria and operating conditions for a number of applications. It is presented for purposes of illustration or preliminary estimate. Actud thickening and classification performance is dependent on particle-size destribution, specific gravity, sludge bed compaction characteristics, and other factors. Final design should be based on bench scale tests. 

Compaction is the oldest, and in its many forms the most used, method for modifying soil properties. On large projects, shallow compaction processes begin with laboratory tests which define the related water content and density that will provide adequate support for the proposed use. Economic factors then determine the type of equipment to be used, from among those which can produce the desired results. Field density tests are then used to measure the progress of field work, and to verify that design values have been attained. 

Deep compaction processes begin with field investigations which delineate the zones where improvement is desirable, and possibly indicate the degree of improvement needed as well as means to measure improvement. Environmental and economic factors then determine the type of equipment and process to be used. Field tests conducted near or at the conclusion of the field work assess the degree of improvement attained.
