Pressure losses in a conduit with a venturi tube

We present the experimental relationships for the coefficient of kinetic flow energy and static pressure as a function of conduit length following a Venturi tube. A formula is proposed for the determination of the coefficient of the hydraulic resistance of the Venturi tube as a function of its structural parameters, as well as a function of the length of the straight segment of the conduit behind the Venturi tube.
