The stack is 13-feet tall with an I.D. of 4 inches. It can be separated to simulate shorter stack heights, while a two-speed blower can alter exit-gas velocities.

Once the board is removed, the number of particles per square meter can be counted to yield the quantitative result of settled particles per square meter. Furthermore, if it is assumed that these particles represent all the particles that would also have impacted a 1-meter depth above the 1-m2 area in which they settled, then the number of particles can now be equated to particles per cubic meter. Lastly, if the mean mass of each paper particle has been measured, the students can then determine the maximum mass per cubic meter concentration of particles that impacted the environment downwind of the stack.
