Fig. 6 -- Limits of fully effective collection for diffusion and impaction
for 10-micropore (a =5x 10-4 cm) and 100-micropore
(a = 5x 107% cm) filters.
The flow conditions and other filter
characteristics assumed are given in the text. Diffusion collects all particles smaller than its limit, while impaction collects all particles larger than its limit.
