The mass of the captured contaminant mCon changes
from 0 to 1.2kg/s during the period from 0 to 1
second.
The filtration efficiency, eps.y, changes from 0.98
to 0.88 during the period from 0 to 0.85 seconds. After 0.85
seconds, the eps.y remains unchanged when
mCon changes. This is because the relative mass of
contaminant captured by the filter already reaches the maximum
value.
