WebSep 26, 2010 · In simple terms, a velocity profile is the distribution of velocities across a pipe. You are probably aware that in an ideal installation, that is one with a great length of smooth straight pipe preceding the measurement point, the velocities are distributed in a regular and known way across the pipe. This is termed a “fully developed” condition.
