What happens to a fluid going from one diameter to a littler one?

What happens to a fluid going from one diameter to a littler one?

(OP)
If a fluid changes diameter passing through a reducer, let's say from 10" to 8" what happens in terms or pressure?
Excuse me for the silly question but in the office someone made doubts arise.

RE: What happens to a fluid going from one diameter to a littler one?

Velocity increases, pressure decreases.

To add to the above, you also loose energy depending on the reducer itself. This is usually calculated based on empirical values. You may ask why? To put it in simple terms; think of the lost energy being transferred into heat due to the increased friction (friction is proportional to velocity).
Refer to any text on fluid mechanics. The fundamentals will be there.

Venturis suck.
