what air speed does a fart come out at?

Having seen a fart lit (see you tube for numerous examples)...the flame was approximately 8 inches long. It took a split second...I'd estimate approximately 2/100ths of a second. Now comes the math:

8 inches per 2/100ths of a sec

=400 inches per second

=24,000 inches per minute

=2,000 feet per minute

=120,000 feet per hour

=22.72 miles per hour

Of course this relies heavily on my anecdotal estimates. Without scientific measurements to back these up I would hesitate using these calculations for anything other than amusement.

Fart travel time depends on atmospheric conditions such as humidity, temperature and wind speed and direction, the molecular weight of the fart particles, and the distance between the fart transmitter and the fart receiver. Farts also disperse (spread out) as they leave the source, and their potency diminishes with dilution. Generally, if the fart is not detected within a few seconds, it will be too dilute for perception and will be lost into the atmosphere forever.

Interesting question.

Buy on of these and then have a batch of beans.
