I just like to imagine the fart particles hitting the people I fart on at the speed of sound. I mean they can't even hear my fart before the shit's hit their face.
My average velocity is for an ideal monoatomic gas. It comes out of the equipartition theorem. E=1/2*m<v^2>=3/2*k*T k is boltzmann's const. T temp in kelvin E is energy. Decided to google and found this page for you. http://www.newton.dep.anl.gov/askasci/chem03/chem03448.htm he claims the average ve...
The average speed for a particle of air(fart) at room temp and normal pressure is something like 1000m/s.
So faster than you can say, "whoever smelt it, dealt it" that fart particle is already inside your coworkers nose.
