Re = 2500 to 2800 account for the significant gravitational deposition.Deposition occurring at half-flow was not very different from full-flow deposition. The effect of enlarging the inlet nozzle diameter from 0.64 cm to 0.99 cm was decreased deposition of the 3.8 |xm mmd aerosol from 43% to 21%. This suggests the use of larger probe nozzles where this is compatible with maintaining isokinetic sampling conditions.
SummaryEfficiencies of four glass fiber filters were found to be greater than 99.9% for aerosols in 1.0 to 4.4 fim mmd range and 99.6% to 99.8% for aerosols near 0.6 jitm mmd.Deposition of solid aerosols in the heated Method 5 probe ranged from 10% for a 2 /xm mmd aerosol to 94% for a 13.4 yum mmd aerosol. Locations where major deposition occurred were the nozzle (about half the total deposit), the leading edge of the probe liner, and the two 90° elbows.

The software was developed by the Tellus Institute, a non-profit research and consulting firm. The project's objective was to provide local solid waste management planners in New York State responsible to develop and implement comprehensive solid waste management plans authorized by the Solid Waste Management Act of 1988, with a WastePlap model specifically tailored to fit the demographic and other characteristics of New York State and to provide training and technical support to the users. Two-day workshops were held in 1992 to introduce planners to the existing versions; subsequently, extensive changes were made to the model and a second set of two-day workshops were held in 1993 to introduct planners to the enhanced version of Wasteplan. Following user evaluations, Wasteplan was further modified to allow users to model systems using a simplified version, and to incorporate report forms required by New York State. A post-project survey of trainees revealed limited regular use of software. Possible reasons include lack of synchronicity w i t h NYSDEC planning process; lack of computer literacy and aptitude among trainees; hardware limitations; s o h a r e user-friendliness; and the work environment of the trainees. A number of recommendations are made to encourage use of Wasteplan by local solid waste management planners.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
