Vpliv lastnosti tekočine in cevi na pretakanje skozi natego

Susman, Primož (author), Čepič, Mojca (mentor)

Magistrsko delo opisuje natego in razjasni določene pojme v povezavi s pretakanjem tekočine. Podrobno so predstavljene meritve za pretakanje različnih tekočin z natego. Teoretično ozadje delovanja natege se v različnih opisih delno razlikuje. Zapišemo lahko, da delovanje natege temelji na razliki tlakov zaradi gravitacijskega privlaka. Podrobno sta opisani dve vrsti pretoka, in sicer laminaren ter turbulenten pretok. Podrobno je opisan Reynoldsov poizkus za določanje vrste pretoka in Reynoldsovo število, ki predstavlja kriterij za določitev teh dveh tokov. Magistrsko delo temelji na meritvah, ki so predstavljene v drugem delu. Izvedene so bile za različne tekočine (voda in sirup) ter za cevi okrogle oblike različnih premerov.

• Title: Effects of liquids' and tubes' properties on flow through the siphon

Abstract

This thesis describes the principles of siphon and elaborates the specific concepts related to the flow of fluids. Measurements of the siphon flow for different liquids and different height differences are presented in detail. The theoretical background describing the siphon mechanism differs slightly in the literature. Generally, the siphon is based on the pressure difference due to the gravitational attraction. In this thesis, two types of flow are described in detail: the laminar flow and the turbulent flow. Furthermore, we provide the detailed description of the Reynold's experiment and the Reynold's number, which is the criterion for determining if the flow is laminar or turbulent. The thesis is based on the measurements presented in the second part. Measurements were carried out for various liquids (water and syrup) and with pipes of different diameters.
