That's true. But the work is performed by the static pressure "around" the particle, while we are dealing with the drop of static pressure of the particle that "receive" work.
I'm trying to understand the microscopic mechanisms that justify the Bernoulli principle. I found an interesting discussion on the site of NASA that tries to describe, in a general way, the mechanism underlying the pressure reduction in favor of the increase in speed. I propose the text in...
Good evening everyone.
Can you tell me if it is possible to mathematically derive the Bernoulli principle from a microscopic analysis?
In particular, in the hypothesis of an incompressible stationary flow, at a constant altitude, it states that:
P + 0.5ρV^2 = cost
Well, in textbooks this...
