Put scoopula through hole and hang paper from scoopula so that it touches the water‚ making sure Ink dot is not submerged. 5. Repeat steps 1-5 using second color of ink. 6. Observe for 15 minutes‚ or until water reaches scoopula. V. Observations and Data: The filter paper was placed above the water with a

and run it through a filter‚ the liquid will pass through the filter and you will be left with the sold. The filter has little holes in it that are small enough to only let liquid through. Filtration is not a technique to separate solids‚ separating solids like that is called sifting. Example of filtration includes your kidney. Kidneys use the same principals but with blood. Another example of filtration is when you make coffee. Making coffee includes the use of a coffee filter. Not that you can do

DSTATCOM applications with nonstiff source is proposed. The proposed topology enables DSTATCOM to have a reduced dc-link voltage without compromising the compensation capability. It uses a series capacitor along with the interfacing inductor and a shunt filter capacitor. With the reduction in dc-link voltage‚ the average switching frequency of the insulated gate bipolar transistor switches of the DSTATCOM is also reduced. Consequently‚ the switching losses in the inverter are reduced. Detailed design aspects

The Purity and Purification of Solids Recrystallization ABSTRACT In this experiment‚ impure adipic acid is purified though recrystallization. The impure adipic acid is dissolved in a solvent. After cooling it is ran through a vacuum filter to separate any moisture. The dry crystals are then weight for percent yield and the melting point range is taken to test the purity. There were two different trials ran in this experiment. The difference between the two was the addition of charcoal in
