How Does the Bernoulli's Theorem Apparatus Work?

[tsukuba]

hello everyone, I am preparing myself to do the Bernoulli's theorem experiment using the apparatus and I want to go to class knowing what I'm doing and how things work. I'm looking online to find how the apparatus works but I can't find anything. I was wondering if maybe one of you could help me out with a link or the best place to find information on the apparatus.
Thank you

What apparatus? One of the simpe examples for Bernoulli effect is a venturi tube.

The one where we measure the static heads of 6 different manometers. We also use a hydraulics bench for water flow
