It consists of a number of organic and inorganic substances in aqueous solution, the polar nature (Polak et al, 1981). Vinassan original and diluted and exhibits different nondissolved solids (NDS) colloidal nature (Brossard and Cortez, 1996). Vinassan rheology has been studied Brookfield RVT measurements disposal Vinassan fuel-oil emulsions (Brossard and Cortez, 1996b). The present contribution is to describe the variations of apparent viscosity Vinassan temperature (T) and rotational speed (n) Brookfield RVT settings, as well as monitor the progress of behavior explanation. Brookfield R.V.T. viscosity data will be used for qualitative assessment of the rheological behavior type, dominant Vinassan solutions tested. The importance of this study provide sufficient data to make it possible for engineers to design Vinassan pipe transport situations, for example, the preparation and combustion vaporizers Vinassan. Most of the data, Vinassan low Brix values ??(up to 5 °), in which it behaves mostly like water. However, high Brix Vinassan (more than 30 °), presents a Newtonian behavior. This observation is very important in the design and suction pipe as it is known from other materials such as molasses in the sugar industry. Viscous as molasses, Vinassan viscosity is highly dependent on water content and temperature, and this is the objective of this study. Vinassan of high-test molasses and dissolved solids concentration of 30 ° Brix was concentrated up to 73o Brix using Buchi Rotavapor vacuum equipment. From the concentrated mother Vinassan, dilutions by adding distilled water to prepare solutions Vinassan with different concentrations (ie, 31.1, 44, 52.4, 66 and 73o Brix). Some of these prepared solutions were centrifuged to separate the NDS Brookfield RVT apparent viscosity Vinassan solutions (with and without NDS) had several temperature and rotational speed (N) viscometer. For this purpose, was used for the cylindrical spindle (? 1, 2, 3, and 4). Viscosity Vinassan temperature (T) and rotational speed (n) Brookfield RVT settings, as well as monitor the progress of behavior explanation. Brookfield R.V.T. viscosity data will be used for qualitative assessment of the rheological behavior type, dominant Vinassan solutions tested. The resulting values ??were processed using linear regression analysis, thus, the relevant mathematical models. All measurements were in triplicate, using the average value calculations. "When Vinassan ³ 66o Brix concentration (from 4 to 7), significant differences a2sb1.gif (94 bytes) values ??are observed in some temperature readings of the various N. It pointed out the differences become smaller as temperature increases. Closer look at the highly concentrated Vinassan (= 66o Brix) viscosity provides additional information. Thus, higher volatility a2sb1.gif (94 bytes) (at a given temperature) of various N observed when they are Vinassan NDS It can be seen by comparing Figures 4 and 5 and Figures 6 and 7. Again increased T-leveling effect. Such behavior can be explained by a critical concentration of a point Vinassan decisions become more structured for the dipole-dipole interaction between their polar Solutes. Other observed changes related to temperature effects, as well as comments on the possible rheological behavior later in the text.</p><strong>About the Author:</strong><br />Visit viscometer.co for all types of <a rel="nofollow" href="http://www.viscometer.co/">viscometer</a> according to your need.<p> Article Source: <a href='http://www.articleseen.com/Article_Use-Rotational-Viscometer-Bench-Study-Vinassan-Viscosity-Temperature-and-Agitation-Rate_127300.aspx'> http://www.articleseen.com/Article_Use Rotational Viscometer Bench Study Vinassan Viscosity Temperature and Agitation Rate_127300.aspx</a></p>
