Speed of fart

The speed of the fart is not consistent I have found through extensive research. The variables I have noted are:

- temperature, the hotter the faster
- volume (db), the quieter the quicker(also the strength is notably stronger)
- volume (cm3), very small volumes seem to travel faster than the speed of light!

Any other variables?

Gas composition.
Ammonia and sulphur dioxide have about half the viscosity of oxygen or nitrogen. One would therefore expect a whiffy one to be faster, everything else being equal.

You do have to take into account the presence of particulate matter though.

and just how do we measure this speed. Is it from the time that the sound reaches one's ears? If so then the speed of sound in the medium might be important as well.

Graham's law states that the rates of effusion of two gases are inversely proportional to the square roots of their molar masses at the same temperature and pressure:

Speed of fart

10m/s seems to be the official answer according to giggle.

No info about smell's speed.
Depending on gender, much quicker I would say.

Scientists have determined that the active component of a fart is carbon dibaxide.

The most powerful event is known as a "Uri Geller Smeller" which can creep around a room bending spoons and stopping clocks.

The amount of solid matter, the more visible the less speed. But on the scale of one to ten the 'more visible' is up there in the response league.

Pressure. Having held one in in a meeting for sone 30 minutes the relief on dropping it as I left was great. Trouble was it was a 30 second low-velocity rumble and as i'd had several pickled eggs for lunch it stripped paintwork in the next room

Pressure build up (the cork in the bottle effect) determines release velocity of a gas as it re-enters the earth's atmosphere.

Most women don't fart as they never stop talking long enough to build up any back pressure

Sadly, living as I do, outnumbered by the female species, I have seen no evidence to back up that theory.

For contrast, consider the miasmic speed of dog fart.
Always silent - always utterly vile - composed of eau de cat vomit, dead bird and various assortments of animal faecal matter he's sniffed and had a nibble of.
But slow and stalking - wafts up to nostril level after the innocent looking little bastard has snuggled in next to your leg as you watch evening TV.
And who gets blamed by the missus?
Not the hound.
Christ woman - how could my guts be responsible for a reek like that?!

I have to comment Tartere. Mrs SOPS two beloved fur balls ( ok I admit, I love them as well) are fed home cooked food my Mrs SOPS. Anst in 11 years they always seem to release minimal odour, as apart from my dog I had before I was married.

Sitting here in my cube at work I just let one rip. A rather loud one at that.
I have found that the volume of said fart corresponds directly to the amount of disgust exhibited by unsuspecting co-workers. Is this, then, a variable?

I will, however, endeavor to perform more such tests throughout the course of the day today.

OK rgbrock1; Now why don`t y`all confess now. You did it deliberately!!

Because as a former Ranger, you would have known that if holed up behind Enemy Lines and you let one go, it could have literally been the death of you!

Therefore you would have been trained to hang onto it, as it were!

I`m calling you out on this one, hear?

Curry, washed down with too much bitter beer? Come on, stop blaming those poor innocent dogs...
