Abstract
Based on the well-established theoretical formulations of
Calvert (1970)
and
Yung et al. (1978)
, graphical tools are developed for estimating the overall collection efficiency of venturi scrubbers under the specified design and operating conditions. Both graphical solutions deliver the accuracy of the original theoretical models, subject to the assumption of a lognormal input particle size distribution. The nomographs produced can be used by environmental engineers for performing convenient analysis of venturi performance and alternative design evaluations, and as part of a wider methodology for compiling particulate matter emission inventories. Combined with the graphical models developed in Part II, the present work sets the stage for conducting size-specific emission inventories (e.g., PM
2.5
, PM
10
, TPM) for sources controlled by venturi scrubbers.
