Summary

[edit]
Description
Македонски: Опит со стаклена инка на кој се демонстрира врската помеѓу динамичкиот и статичкиот притисок, односно Бернулиевата равенка. Кога се дува, тогаш динамичкиот притисок помеѓу плочата и хартијата се зголемува, затоа што тој зависи од квадратот на брзината. Согласно Бернулиевата равенка, зголемувањето на динамичкиот притисок подразбира намалување на статичкиот притисок, односно помеѓу плочата и хартијата се намалува статичкиот притисок што ја лепи хартијата за плочата. Изведено и објаснето од проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Demonstration of a relation between dynamic and static pressure, i.e. Bernoulli's principle. When blowing, the dynamic pressure between the paper and the plate increases. According to the Bernoulli's principle, in this case the static pressure between the plate and the paper decreases, which forces the paper to stick to the plate. Performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Démonstration de la relation entre la pression statique et dynamique (principe de Bernoulli).
Lorsque l'on souffle à travers le tube, la pression dynamique entre la plaque et le papier augmente. D'après le principe de Bernoulli, en conséquence, la pression statique diminue entre les deux, ce qui amène le papier à adhérer à la plaque.
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.
Українська: Демонстрація співвідношення між динамічним і статичним тиском, тобто закону Бернуллі. Коли дмеш, динамічний тиск між аркушем і пластиною збільшується. Відповідно до принципу Бернуллі, статичний тиск зменшується, що змушує папір прилипнути до пластини.
Română: Demonstrație a relației între presiunea dinamică și cea statică, respectiv principiul lui Bernoulli. Când se suflă, presiunea dinamică între hârtie și placa metalică crește. Conform principiului lui Bernoulli, în acest caz presiunea statică între placă și hârtie scade, ceea ce face ca hârtia să adere la placă. Efectuat de prof. Oliver Zajkov de la Institutul de Fizică al Universității Sfinții Chiril și Metodiu din Skopje, Macedonia.
