Wet grinding was similar to dry grinding, the carborundum paper on the base and glass slide were soaked in distilled water and few drops of water were added after every 10–20 s during grinding. Wet grinding started with a paper grade of 180 cc and shifted to 220 and 240 cc after 3–4 min. Fig. 2.11 shows the steps of dipping carborundum base ...

An emission factor relates the quantity (weight) of pollutants emitted to a unit of activity of the source. The uses for the emission factors reported in AP-42 include: 1. Estimates of area-wide emissions; 2. Estimates of emissions for a specific facility; and 3. Evaluation of emissions relative to ambient air quality.
