| Abstract |
The report describes a cascade impactor data reduction system written in the Fortran IV language. The overall system incorporates six programs: MPPROG, SPLIN1, GRAPH, STATIS, PENTRA, and PENLOG. Impactor design, particulate catch information, and sampling conditions from single impactor runs are used to calculate particle size distributions. MPPROG and SPLIN1 perform data analyses and make curve fits. GRAPH is totally devoted to various forms of graphical presentation of the calculated distributions. The particle size distributions can be output in several forms. STATIS averages data from multiple impactor runs under a common condition. PENTRA or PENLOG calculates the control device penetration and/or efficiency. The plotting routines have been written for a PDP15/76 computer and are not compatible with other computing systems without modification. |
