when you run your taps the flow of water gets narrower as it nears the sink, but why?

It's similar reasoning to the garden hose answer.  If you have a gallon of water leaving your faucet each second, you must also have a gallon of water hitting your sink each second.  However, as the water falls from the faucet to the sink, it speeds up due to gravity.  In order for the faster water at the sink to strike at a rate of 1 gallon/second, it must be a narrower stream than at the faucet.

What jpetruccelli wrote, in formula:

Q = A*v

Q = flux of water (gallons/seconds)

A = area of an orthogonal section of water flow

v = water speed.
