Yahoo spits up three right at the top. They have varying degrees of
technospeak, so I'm posting all three:

http://www.svce.ac.in/~msubbu/FM-WebBook/Unit-III/PitotTube.htm
http://www.efunda.com/designstandards/sensors/pitot_tubes/pitot_tubes_theory.cfm
Of course, the go-to website on how stuff works is, of course,
www.howstuffworks.com:

They may not always have the best description possible, but they certainly have
the widest variety, so there's usually something applicable.
One important note on pitot tubes is that they don't indicate your true speed in
relation to the ground, but rather to the air around you (I'm guessing water for
boats). If you're flying into a 100mph headwind, you'll get the same airspeed
reading as you would when flying downwind going 200mph faster. The only way to
measure truly accurate speed in relation to the ground would be to go by GPS
readings.
