Question:
The dust-laden air of Prob. 29.11 is passed through an impingement separator at a linear velocity of 8 m/s. The separator consists essentially of ribbons 25 mm wide. What is the maximum fraction of the particles that can be removed by the first row of ribbons, which covers 50 percent of the cross-sectional area of the duct?
Prob. 29.11
Air carrying particles of density 1.800 kg/m3 and an average diameter of 20 μm enters a cyclone at a linear velocity of 18 m/s. The diameter of the cyclone is 600 mm.
(a) What is the approximate separation factor for this cyclone?
(b) What fraction of the particles will be removed from the gas stream?
