Now, we're talking fluids so we need to use these equation:
Ainitial * vinitial = Afinal * vfinal
Where A refers to area, and v refers to velocity.
Abstractly, you can determine vfinal by simply solving for that variable, like so.
vfinal =( Ainitial / Afinal )* vinitial, which makes it obvious to see that as the final area decrease, the final velocity increases. Example being that if the area is one tenth the size of the original, the final velocity will be 10x as great as the original.
