The manual describes a microcomputer program written to estimate instack opacity from ducted sources. Input data required to run the program are the particle size distribution, particle refractive index, mass emission concentration, wavelength of light, particle density, and stack diameter. The particle size distribution may be entered either as a histogram of particle diameter and fraction-greater-than-stated diameter or as log normal particle size distribution. The program calculates and displays the in-stack opacity. The program is written in the BASIC computer language and is specifically designed for the TRS-80 Model I, II, and IV computers. A moderate effort will be required to convert the programs to the IBM-PC and similar computers.
