Velocity Profile: Fluid Mechanics Explained

AI Thread Summary
A velocity profile in fluid mechanics describes how fluid velocity varies across different points in a flow field. The ratio of fluid velocity to a reference velocity is used to normalize measurements and facilitate comparisons, even though the reference velocity may seem arbitrary. This ratio often reflects experimental observations and helps in analyzing flow behavior. Understanding these profiles is crucial for applications in engineering and fluid dynamics. The discussion emphasizes the importance of clarity in questions related to fluid mechanics concepts.

What is a velocity profile in fluid mechanics? Why do they give you a ratio between the fluids velocity and a random reference velocity and why is it equal to a completely arbitrary function?
Does the ratio equal a function because it is an experimental fact?

Can you give a specific example of what is troubling you? It is difficult to understand your question otherwise.
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
