Vliv diferenčního tlaku a jiných proudových a geometrických parametrů na Venturiho trubici

Abstract

The bachelor thesis deals with the flow through a Venturi tube and flow measurement. The introduction explains the theory of flow and methods of flow measurement. The practical part describes the principle of operation of the Venturi tube, its construction, manufacturing and a schematic of a classical Venturi tube is created with a description of its individual parts. In the second part of the practical section, a given example is calculated, in which variables such as differential pressure, geometry, pressure in the ingoing fluid and density are gradually changed, and an analysis of the influence of these changes is performed.
