THE CALCULUS OF THE CONTRACTION COEFFICIENT OF AN ORIFICE AND THE GRAPHYCAL RESULTS REPRESENTATION WITH SIGMA PLOT PROGRAMME
This paper presents the continuation of the studies from the last two articles presented at the last two Sebeș conferences. The authors used the same numerical method to integrate the Navier-Stokes equations and the presentation is done this time using a Sigma Plot programme. The study is performed with a combination of symmetric and asymmetric orifices at the same Reynolds number. The authors used again the method of finite differences to determine the flow through a tank and through the contracted section of the liquid passing an orifice.
