- Blue = Fabric/Thread
- Green = Mucus without viral particles
- Red = Mucus with viral particles
According to this wiki article: Coronavirus: "The diameter of the virus particles is around 120 nm." (0.12 microns)
1 pixel = 1 micron (1/1000000 meters) which is the "base unit" of mesure used in this simulation - meaning that up to (1 / ~0.12 = ~8.33 * ~8.33 * ~8.33 = ~578.009537) viral particles can fit in each 1 pixel red dot.
The largest unit used is 1".
1 micron is about ~0.0000393701 inches (smaller than you can see).
For reference, human hair is between 15 to 180 microns.
According to a google search, a penny is ~19,053 microns in diameter.
Droplet size resolution between 1 to 10 pixel/microns.
