Answer:
No, I disagree
Explanation:
The average velocity in a circular pipe in fully developed laminar flow cannot be defined by simply measuring the velocity at R/2 (midway between the wall surface and the centerline). Vmax/2 is the mean velocity, but the velocity at midway between the wall surface and the centerline is
[tex]V(R/2)= V_{max}(1-\frac{r^2}{R^2} )_{r= R/2 }=\frac{3V_{max}}{4}[/tex]
Where R represent the circular pipe radius and r is a local radial distance measured from center of the pipe to any desired point
