**drwls**, Tuesday, July 20, 2010 at 11:38pmAccording to what is called the continuity equation, the product of

(density)(cross sectional area)(velocity)

is a constant in steady-state flow.

For a liquid such as water, you can assume that the density is constant.

Therefore A*V = constant

Since Area is proprtional to diameter ^2,

D^2*V = constant

Now do the numbers.
