In cyclone dust collectors used in agricultural grain processing, particle collection efficiency increases with:
Options:
(A) Higher particle density, larger particle diameter, and higher inlet air velocity
(B) Lower particle density
(C) Larger cyclone diameter
(D) Lower inlet velocity
Answer Key:
A
Step-by-Step Solution & Explanation
Centrifugal separation force is $F_c = m v^2 / r = \frac{\pi}{6} d_p^3 \rho_p v^2 / r$, which increases with grain diameter $d_p$, particle density $\rho_p$, and tangential velocity $v$.
