Additional information about bernoulli and/or venturi effect...?

Question

I am working on a system operating with venturi effect of the water. Anybody have additional knowledge of venturi effects of floving water in a tube?

Answer 1

Flowing water possesses potential and kinetic energy. Pressure represents potential energy because it could apply a force (to a piston?) and do work. Velocity represents kinetic energy which is stored in the velocity of mass. Expect that within a venturi tube (neglecting fluid and wall friction) energy will neither be created nor destroyed but can be converted. If velocity (kinetic energy) increases to pass through a restricted smooth venturi neck, pressure (potential energy) must decrease. A moving pendulum also constantly converts potential energy (height) to kinetic energy (velocity) with each stroke of the bob.
