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:
“Nature centres into balls,
And her proud ephemerals,
Fast to surface and outside,
Scan the profile of the sphere;
Knew they what that signified,
A new genesis were here.”
—Ralph Waldo Emerson (1803–1882)
“If one doubts whether Grecian valor and patriotism are not a fiction of the poets, he may go to Athens and see still upon the walls of the temple of Minerva the circular marks made by the shields taken from the enemy in the Persian war, which were suspended there. We have not far to seek for living and unquestionable evidence. The very dust takes shape and confirms some story which we had read.”
—Henry David Thoreau (1817–1862)
“When you can pipe that merry old strain,
Robert of Lincoln, come back again.”
—William Cullen Bryant (1794–1878)
