Question
What is a general collection efficiency curve for an inertial impactor looks like? Please make a sketch. For a given sampling flow rate, how is the curve changed when 1) the nozzle size is decreased or 2) the inlet pressure is reduced from 1 atm to 0.1 atm?
Expert Solution
Step 1
Inertial impactors are widely used for size fractionated sampling of aerosols. Theoretical analysis of the inertial impactors predicted the cut off diameter and the shape of the collection efficiency curves reasonably well for the liquid particles.
The general collection efficiency curve for Inertial impactor as shown in below figure.
