Anyone thirsty? Today's Photo of the Day, a stream of water from a fireboat, comes to us from TheClayTaurus. Besides its vibrant colors, I like how you can see the fluid dynamics at work. Check out the large version for a good view of the water jet narrowing just after it leaves the nozzle. This also reminds us that the city best get working on its hydrants so we don't have any repeats of the Georgetown Library fiasco. EXIF

Exactly what part of fluid dynamics is that showing? A link would be nice :)
Check

and
en.wikipedia.org/wiki/Nozzle
FWIW, there isn't actually a propper nozzle attached, however the principle somewhat applies because the monitor itself has a bit of convergence at the exit point for the water.
Cheers! :)
This photo is demonstrating more than one principle in fluid dynamics, one of them being:
Pressure = Force / Area
In that equation, as the area of the hole is decreased or the force is increased, the pressure increases.
So if I had a choice of either wading in Rock Creek or standing in front of a pipe that had Rock Creek running through it, I'd choose to wade in it (assuming I wasn't afraid of catching a water born disease).
