A velocity profile in fluid mechanics describes the variation of fluid velocity across a specific cross-section of flow. It provides a ratio between the fluid's velocity and a reference velocity, which is often an arbitrary function determined through experimental data. Understanding this concept is crucial for analyzing fluid behavior in various applications, including pipe flow and aerodynamic studies. The discussion emphasizes the importance of empirical evidence in establishing these relationships.

CrazyNeutrino said: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?
