the separation of a suspension into a supernatant clear fluid and a rather dense slurry containing a higher concentration of solid. According to Perry ()‚ sedimentation is the partial separation or concentration of suspended solid particles from a liquid by gravity settling. This field may be divided into the functional operations of thickening‚ whose purpose is to increase the concentration of suspended solids in a feed stream; and clarification whose purpose is to remove a relatively small quantity

vertical U tube of uniform cross section contains mercury in both of its arms. A glycerine (d = 1.3 g/cm3) column of length 10cm is introduced into one of the arms. Oil of density 0.8g/cm3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6 g/cm3.

to determine the density of solids and liquids using Archimedes’ Principle. For the density of solids‚ they had made use of spring balance to measure the mass of the metal samples‚ which were tied via string‚ in air and when immersed inside a 2000mL beaker‚ where H2O lies. They had computed the density of each sample metal using the formula: ϱs = maϱw / ma - mw and computed a percentage error. As for the density of liquids‚ they had filled a graduated cylinder with 250mL liquid sample and had immersed

9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation
