Confusion in Bernoulli Principle/ Root Beer example. (PhysicsLibrary/Fluids/BernoulliPrinciple)
In the article on fluids and Bernoulli's principle they explain that if the pressure is lower at one point (where the pipe is narrower), the velocity is higher as opposed to another point where the velocity is lower and the pressure is higher (where the pipe is wider).
However further down in the root beer example there is a case where the pressure at point 1 (narrow area) is 12000Pa and the velocity is 3m/s and the velocity at point 2 (wide area) is 0.75m/s. So I would have understood that due to the above (lower velocity -> higher pressure) however the result of pressure 2 is 4080Pa, lower than P1 where the velocity is higher.
"Bernoulli's principle: At points along a horizontal streamline, higher pressure regions have lower fluid speed and lower pressure regions have higher fluid speed."
I hope you can clarify my doubt.
