Abstract
We perform the comparative and statistical analyses of the discharge coefficients of critical nozzles with toroidal branch pipes and discuss the main approaches aimed at the evaluation of the discharge coefficients. We present the equations for the dependences used to describe the behavior of the discharge coefficients of critical nozzles as functions of the Reynolds number. By using an example of critical Venturi nozzles, we study the factors affecting the accuracy of measurements of the gas flow rate.
