Description:
The handbook is intended for persons concerned with air pollution measurement studies of stationary industrial sources. It gives detailed descriptions of 22 different programs written specifically for the Hewlett Packard Model HP-65 card-programmable pocket calculator. For each program there is: a general description, formulas used in the problem solution, numerical examples, user instructions, and program listings. Areas covered include: Methods 1 through 8 of the EPA Test Codes (Federal Register, 12/23/71), calbiration of a flame photometric detector by the permeation tube technique, determination of channel concentrations for a droplet measuring device, resistivity and electric field strength measurements, determination of stack velocity, nozzle diameter, and isokinetic delta H for a high volume stack sampler, and several programs for cascade impactors. Cascade impactor programs include: determination of impactor stage cut points, calculation of the square root of the Stokes number for round-jet and for rectangular-slot geometries, nozzle selection and determination of delta H for isokinetic sampling, determining of sampling time required to collect 50 mg total sample, determination of impactor flow rate, sample volume, and mass loading, and calculation of cumulative concentration curves and their differentials.
