An excerpt from Cascade Impactor Data Reduction with TI-59 Programmable Calculator, EPA, EPA-600/7-78-226, NOV 1978, 112 pgs.
" ABSTRACT
This report is intended to provide useful tools for obtaining particle size distributions and graded penetration data from cascade impactor measurements. The programs calculate impactor aerodynamic cut points, total mass collected by the impactor, cumulative mass fraction less than for each stage, log-normal size distribution parameters for the data, and graded penetration. These programs are written specifically for the Texas Instruments SR-52 and TI-59 programmable calculators and the PC-lOOA printer. A general discussion of the program, an example problem, program listing, and user instructions are provided for each program. …
…
TI-59 PROGRAM SET
GENERAL DISCUSSION
The TI-59 program set is contained on five cards. Four cards are used to store program instructions and the fifth card is used to store the impactor stage constants and the constants for the log-normal transformation. The Master Library Module is used as a subroutine in the data reduction program set. … "
