I have read and understood the explanation of the Bernoulli principle based on conservation of energy, but what I would like is a more intuitive way of picturing just how the reduced pressure develops in, say, a venturi tube.
I want to be able to mentally track an element of the fluid and see, in my mind's eye, why a "slice" of the fluid flow presses on the walls with less and less pressure as it approaches the narrowest point. Is there an intuitive explanation of this sort?
Edit: I realized that I do not really understand it even in terms of conservation of energy. My problem is with dynamic energy : is it just the kinetic energy of an element?
