In this chapter we show that fluids behave asymmetric between constriction and diffusion. modeling that behavior mechanically in a venturi nozzle, this requests forces / pressure being not equilibrated that motion can happen. a drop in static pressure in a mechanical system cannot be. this would violate newtons 3rd law of motion. finally this lets to the result, that incompressible fluid do not hold a energetic potential, because they do not have an internal source of energy. all energy or work comes thus from an external source which creates the pressure drop. wall friction as source of pressure loss in insufficient. i'll maybe will dedicate another chapter that will focus on the energy lost by pressure drop and will show that the lose energy will be too much of that what's possible by viscous sheering of the fluid itself.
