Limited Droplet size:

When the gas stream enters in the curved channel formed by the M/E, droplet will be separated by the gravity force, centrifugal force and drag force. If some certain size of droplet can 99.9% escape from the M/E, it is called limited droplet size. The droplet above the Limited droplet size will be removed, otherwise only 50% probability to be removed by M/E. The limited droplet size will be reduce when the gas velocity increased.

Assumed limited droplet size is 20μm

A= 15μm，Escape from M/E

B =30μm，Removed by M/E
