on differences in physical properties such as decantation‚ filtration‚ extraction and sublimation. The process of separating a liquid from a solid (sediment) by gently pouring the liquid from the solid so as not to disturb the solid is Decantation. Filtration is the process of separating a solid from liquid by means of a porous substance –a filter- which allows the liquid to pass through but not the solid. Extraction is the separation of a substance from a mixture by preferentially dissolving that

DISCUSSION | 9 | CONCLUSION | 10 | REFERENCES | 11 | APPENDIX | 12 | Summary This study was undertaken to investigate the characteristics of a Centrifugal pump. The Centrifugal pump is largely used in petrochemical industries to move liquids around the plants and refineries. Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work

existing fluid models tend to be either too inaccurate‚ or at least highly non-generic for most practical applications. This article introduces simple‚ yet accurate approaches for measuring and predicting the most important dynamic fluid parameters: bulk modulus‚ density and speed of sound in fluid. The methods are basically applicable to any standard hydraulic fluid‚ without any extra system-related constraints‚ at least at the presented conditions. The studied pressure range reaches 1500 bar‚ and the temperatures

(non-DIS placement) Microencapsulation Techniques and Applications Student Name: Photchara Chawasap‚ B118708 Date: 26/9/2013 Word Count: 8321 SUMMARY Microencapsulation is a technique in which active ingredients solid or liquid are coated within a second material for the purpose of protecting the active ingredient from the surrounding environment. The coated core material is called a ‘microcapsule’. The active ingredient is the core material and the surrounding material

must reach 41°F/5°C or below within an additional four hours‚ for a total cooling time of six hours. The proper way to cool hot liquids is to place them in a metal container in an ice water bath that reaches the same level as the liquid inside the container. Stir the liquid in the container frequently so that the warmer liquid at the center mixes with the cooler liquid at the outside edges of the container‚ bringing the overall temperature down more rapidly. Semisolid and solid foods should be refrigerated

The following equation shows the relation of the V_∅ of a binary solution with density‚ Equation 1 The notations which are used in Equation 1 are as follows: mi: Molality of solute i‚ F: Density of the binary solution‚ ρ_w: Density of water. In general‚ In order to yield apparent molal volumes at infinite dilutionV_∅^∞‚ the apparent molar volumes V_∅ of aqueous electrolyte solutions are extrapolated to

“Hydraulic Fracturing or Fracking is a process in which fractures in rocks below the earth’s surface are opened and widened by injecting chemicals and liquids at high pressure”(Dictionary). This type of mining is used to extract natural gas and oil by drilling a mile or more below the surface. Fracking has been “commercially used for 65 years”(Introduction)‚ supplying Americans energy. Hydraulic Fracturing has allowed for the increase in supplies of oil and natural gas. It is currently the best and
