In a cyclone separator, the separation factor Sr (ratio of centrifugal to gravitational force) is defined at radial distance r from the centre. Which statement is INCORRECT?
- Sr depends on mass of the particle
- BSr depends on the acceleration due to gravity
- CSr depends on tangential velocity of the particle
- DSr depends on the radial location (r) of the particle
Explanation
Sr=(mv_t²/r)/(mg)=v_t²/(rg) — the particle mass cancels out entirely, so Sr does NOT depend on mass.
