Velocity Profile in A Circular Pipe
Just like a Newtonian fluid in a circular pipe gives a quadratic velocity profile (see Hagen–Poiseuille equation), a power-law fluid will result in a power-law velocity profile,
where is the (radially) local axial velocity, is the pressure gradient along the pipe, and is the pipe radius.

Famous quotes containing the words profile, circular and/or pipe:
“Actor: Electrician, a little more this way with that spotlight. What are you trying to do, ruin my profile?
Electrician: Your profile was ruined the day you were born.”
—James Gleason (1886–1959)
“Loving a baby is a circular business, a kind of feedback loop. The more you give the more you get and the more you get the more you feel like giving.”
—Penelope Leach (20th century)
“I am dead against art’s being self-expression. I see an inherent failure in any story which fails to detach itself from the author—detach itself in the sense that a well-blown soap-bubble detaches itself from the bowl of the blower’s pipe and spherically takes off into the air as a new, whole, pure, iridescent world. Whereas the ill-blown bubble, as children know, timidly adheres to the bowl’s lip, then either bursts or sinks flatly back again.”
—Elizabeth Bowen (1899–1973)
