Design a single cyclone (Swift Conventional) to handle 20,000cfm (at 250F and 1atm) of air contaminated with the particles :
Particulate density =1200 kg/m^3 gas density = .90 kg/m^3
gas viscosity =.06 kg/m-hr and inlet gas velocity 25m/s
Size Range: 0-4, 4-10, 10-20, 20-40, 40-80, >80
Mass percent 3.0, 10.0, 30.0, 40.0, 15.0, 2.0
The required efficiency must be between 75% and 80% and the maximum allowable pressure drop is 8.0 in. H2O.
