cyclone is having width of 20 cm, length of 30 cm and diameter 0.75 m. Number of effective turns in the cyclone is 10. Polluted air sample (density-1.5 kg/m) is passed through this cyclone at 15 m/s. Pollutants in this sample have average particle size of 8 um and density of 1.5 g/cc. Air is at 25C and its viscosity is 0.8 kg/m.h. Assume constant "K" as 13. Determine (i) cut point diameter (whole numbers in um), (ii) separation factor (in whole numbers) and (iii) the pressure drop (nearest whole number in Pa) of the cyclone. (iv) Explain why this cyclone is highly efficient.
