Taking the acceleration due to gravity to be 10 m/s², the separation factor of a cyclone 0.5 m in diameter and having a tangential velocity of 20 m/s near the wall is _____
160(± 5 accepted)
Explanation
Separation factor = centrifugal acceleration / gravitational acceleration = vt²/(r·g). With r=D/2=0.25 m, vt=20 m/s: Sc=20²/(0.25×10)=400/2.5=160.
