For example, if the probe velocity, pressure, temperature, and dimensional parameters indicate a
high Reynolds number, it means the velocity profile will be relatively flat, and thus the single-point
velocity measurement at the probe will be a fair representation of velocity across the entire width of
the pipe. However, if the parameters indicate a low Reynolds number, it means the velocity profile
will have a more pronounced “bullet” shape, and therefore the velocities near the pipe walls will be
substantially less than the velocity at the center. The flow computer uses this predicted velocity
profile to interpret the probe’s single-point velocity measurement and calculate the average velocity
of the entire flowstream.
