Determination of Theoretical Sampling Efficiencies for Aspirated Particulate Matter through a DRES Sampling Probe in Anisokinetic Flow.

Abstract

Sampling efficiencies are calculated for an aspirated particulate matter sampling probe under various conditions of anisokinetic flow. A mathematical model developed for the purpose was used to obtain results for a wide range of particle sizes and flow velocities. The results can be used to predict or correct sampling errors in field or laboratory experiments. Using the same test parameters as in previous experimental tests by other workers, sampling efficiencies were calculated and the results were found to agree favorably with the results of the experiments.
