Summary
| Description |
Македонски: Опит со стаклена инка на кој се демонстрира врската помеѓу динамичкиот и статичкиот притисок, односно Бернулиевата равенка. Кога во инката не се дува, топчето паѓа. Ако се дува во инката, тогаш динамичкиот притисок помеѓу топчето и ѕидовите на инката се зголемува (тој зависи од квадратот на брзината). Согласно Бернулиевата равенка, зголемувањето на динамичкиот притисок подразбира намалување на статичкиот притисок во, односно помеѓу топчето и инката се намалува статичкиот притисок што го спречува топчето да падне. 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. The ball falls of the funnel. But, when blowing, the dynamic pressure increases. According to the Bernoulli's principle, in this case the static pressure between the ball and the walls of the funnel decreases, which holds the ball, preventing it from falling. Performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Démonstration du principe de Bernoulli à l'aide d'un tube de Venturi. Ainsi, lorsque de l'air est soufflé dans le tube, la pression diminue dans ce dernier. La pression étant moindre à la sortie du tube, une force vers le haut s'exerce, ce qui maintient la balle et le cône de papier dans les airs. 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. |
