L'équation de Bernoulli est simplement une forme plus générale et plus mathématique du principe de Bernoulli qui prend en compte les variations d'énergie potentielle de pesanteur. Elle sera démontrée dans le paragraphe suivant mais dans un premier temps on regarde à quoi elle ressemble, ce qu'elle signifie et dans quel contexte l'utiliser.
A equação de Bernoulli é, em sua essência, uma forma mais geral e matemática do princípio de Bernoulli que também leva em consideração variações na energia potencial gravitacional. Vamos derivar essa equação na próxima seção, mas antes disso, vamos dar uma olhada na equação de Bernoulli e ver o que ela diz e como podemos usá-la.
Bernoulli's equation is an equation from fluid mechanics that describes the relationship between pressure, velocity, and height in an ideal, incompressible fluid. Learn how to derive Bernoulli’s equation by looking at the example of the flow of fluid through a pipe, using the law of conservation of energy to explain how various factors (such as pressure, area, velocity, and height) influence ...
Sal continues on from the previous video to derive the mean and variance formulas for the Bernoulli distribution.
Bernoulli's principle is a seemingly counterintuitive statement about how the speed of a fluid relates to the pressure of the fluid. Many people feel like Bernoulli's principle shouldn't be correct, but this might be due to a misunderstanding about what Bernoulli's principle actually says. Bernoulli's principle states the following,
