Example 9-2: Determining particle removal efficiency in cyclones An air stream with flow rate of 7 m/s is passed through a cyclone of standard proportions. The diameter d the cyclone is 2.0 m, and the air temperature is 77'C. (a) Determine the removal efficiency for a particle with a density of 1.5 g/cm and diameter of 10 um. (b) Determine the collection efficiency based on the above if a bank of 64 cyclones with diameters of 24 cm are used instead of the single large unit.
