I know the topic has been dealt in the past, I read it but still couldn't extrapolate a satisfying answer.(adsbygoogle = window.adsbygoogle || []).push({});

I would like to know how Berboulli equation applies to a hose without restrictions in which fluid (water) exits at atmospheric pressure, the typical garden situation without any nozzle.

I have, let's suppose 3 bars at the initial section (1) and 0 bars (atmospheric pressure) at the discharge section (2). We consider z1 = z2, p1 = 3 bars, p2 = 0, the question is: does v1 = v2?

The second question is: if I put my finger at the exit section causing a little reduction in the section (but still allowing water flow) what happens to pressure??

Many thanks, Ferex
