Scientists at the Georgia Institute of Technology in Atlanta have arrived at a universal law of urination that explains why dogs, goats, cows and elephants male and female all take approximately 21 seconds to empty their bladders. According to New Scientist, the research team studied local zoo animals and hours of YouTube videos to arrive at their results.
Patricia Yang and her colleagues study fluid dynamics and specifically how animals interact with liquids. The team previously used high-speed imaging to determine how dogs shake themselves dry.
The new research took into account each animals mass, bladder pressure and urethra size as it studied videos of several different species of mammals peeing. Investigators were able to create a mathematical model of urinary systems across species, explaining why divergent groups of mammals spend roughly the same amount of time emptying their bladders.
Previous models, explained New Scientist, have only considered the effects of bladder pressure, but the length of the urethra turns out to be important as well. Yang told the publications, Most of the research is on humans or animals smaller than humans, and in these animals, gravity is not a huge factor in the rate at which the bladder empties.

Is that I Nobel I smell? I hope that's what that smell is.

(23,018 posts)Animals are vulnerable while performing bodily functions. Perhaps 21 seconds is the average time of urination by all animals to avoid being killed by some other animal. A bigger bladder causing longer urination... those animals got eaten out of the evolutionary chain. Just a theory though...

(11,785 posts)I hope they're somehow filming this, but I can imagine some research grunt whose job is hanging around, waiting for animals to piss. Then again, fast-forwarding through tape looking for urinating animals is weird enough.

No?!!!

(43,890 posts)Approximately half of men in their 50s and as many as 90 percent of men in their 70s and 80s have enlarged prostates.
That sounds like a normal age progression event to me.

(24,605 posts)that these highly educated individuals spent countless hours watching You Tube videos of animal peeing or that hours of such videos even EXIST on You Tube.

All in all he spends approximately 12-14 minutes emptying his bladder. Hell, he trys to empty his bladder when there can't possibly be anything left.

(61,698 posts)Try Yellow Jackets for Georgia Tech. The Bulldogs are the mascot for UGA, or University of Georgia. Different university.
I happen to be an alumnus of UGA.
Leave it to Tech.... meaning, to do something as stupid as studying mammalian pissing volume/time
Idiotic "biology" at Tech.
They should stick to electrical or chemical engineering.
Real biologists go to UGA.
Go DAWGS!
I think so....
Ilsa
(61,698 posts)I usually yell for the Dawgs too.
(Since GTech was the focus of the thread, it looked as if you were calling them "Dawgs".)

to see if I fit the norm. (And you thought the only pissing contests were in politics!)
P.S.: 24.9 seconds
told you they were wrong!
