Noticed that in some range we have straight line either when we look at energy spectrum distribution vs different length scales or plots that u gave in the video.. As I understood correctly, either self-similar behavior can be shown as a straight line in log-log graph; as well as if we are dealing with some dimensionless quantities; as well as we can approximated behavior of a process with power-law , pareto of log-normal distribution in some range (implying statistical approach of course..)

How does one get centerline velocity experimentally ?
You can place a hotwire at centerline.
