Summary

Description
Македонски: Демонстрација на вискозност на течност, односно внатрешно триење. Во цевката е ставен глицерин, во долната половина од глицеринот е ставена боја за да биде видлив ефектот. По оската на цевката течноста тече со најголема брзина, затоа што тука внатрешното триење е најмало. Како се оддалечуваме од оската, така се зголемува внатрешното триење и брзината на течење на течноста се намалува. Тоа може да се забележи од закривеноста на граничната површина помеѓу обоениот и необоениот дел од глицеринот. Изведено и објаснето од проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Experiment demonstrating viscosity of a fluid i.e. internal friction. There is glycerin flowing in the pipe. The lower part of the glycerin is colored in order to make the effect visible. Along the axis the glycerin flows with greatest speed, since the internal friction is lowest. Farther from the axis the internal friction increases, which lowers the speed. It can be seen by the curved boundary surface between the colored and transparent glycerin. Performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Expérience sur la viscosité.
Du glycérol, dont une partie est coloré en bleu, est placé dans un tube vertical.
Expérience réalisée et expliquée par le professeur Oliver Zajkov de l'Institut de physique de l'université Saints-Cyrille-et-Méthode de Skopje de Macédoine.
Română: Experiment ce ilustrează viscozitatea unui fluid, adică frecarea internă. Prin țeavă curge glicerină. Partea inferioară a glicerinei este colorată pentru a face efectul vizibil. De-a lungul axei, glicerina curge cu viteza cea mai mare, deci frecarea internă este minimă. Mai departe de axă, frecarea internă crește, și viteza este mai mică. Se poate vedea prin suprafața de contact curbată între glicerina colorată și cea transparentă. Efectuat de prof. Oliver Zajkov de la Institutul de Fizică al Universității Sfinții Chiril și Metodiu din Skopje, Macedonia.
