The report should be useful to persons concerned with Air Pollution Measurement Studies of Stationary Industrial Sources. It gives detailed descriptions of 22 separate programs, written specifically for the Hewlett Packard Model HP-25 manually programmable pocket calculator. Each program includes a general description, formulas used in the problem solution, program listings, user instructions, and numerical examples. Areas covered include: Methods 1 through 8 of the EPA Test Codes (Federal Register, December 23, 1971), calibrating a flame photometric detector by the permeation tube technique, determining channel concentrations for a droplet measuring device, resistivity and electric field strength measurements, determining stack velocity, nozzle diameter, and isokinetic delta H for a high-volume stack sampler, and several cascade impactor programs. Cascade impactor programs include: determining impactor stage cut points, calculating the square root of the Stokes number for round jet and for rectangular slot geometries, nozzle selection and determining delta H for isokinetic sampling, determining sampling time required to collect 50 mg total sample, determining impactor flow rate, sample volume, and mass loading, and calculating cumulative concentration curves and their differentials.
