Don't be silly I never said such a thing. BUT energy conservation laws
do apply.

BUT energy conservation laws does not consider friction losses,
compression and turbulence.

They are a result of a mathematical construction for an non existing
mathematical perfect fluid.

Prof. em John D. Anderson,Maryland University, writes in one of his
aerodynamic books, that Bernoulli equation can be used only for a
straight centerline of a venturi pipe, and then you have not
considered the compressibility of the fluid along that centerline!
