Resumen de Flawed Applications of Bernoulli’s Principle
Panagiotis Koumaras, Georgios Primerakis
One of the most popular demonstration experiments pertaining to Bernoulli’s principle is the production of a water spray by using a vertical plastic straw immersed in a glass of water and a horizontal straw to blow air towards the top edge of the vertical one. A more general version of this phenomenon, appearing also in school physics problems, is the determination of the rise of the water level h in the straw (see Fig. 1).
