Stokes's Law George Gabriel Stokes was an Irish-born mathematician who spent much of his life working with fluid properties. He is most famous for his work describing the motion of a sphere through viscous fluids. This lead to the the development of Stokes's Law. This equation shows the force needed to move a small sphere through a continuous, quiescent fluid at a certain velocity. It is based primarily on the radius of the sphere and the viscosity of the fluid. The equation he developed is F=6(pi)RnVc, where R is the radius of the sphere, n is the viscosity, and Vc is the velocity through a continuous fluid. This equation can be manipulated to calculate the viscosity of the fluid. An explanation is given in the partial lab write-up linked below. Stokes's work was further refined later to account for "wall (or edge) effects" and "end effects" by Gibson and Jacobs in 1920. These phenomena result in a slower observed velocity because the medium is not continuous. The wall effect correction accounts for the compression of the liquid against the sides of the container holding the fluid as the sphere moves through. This is based on a ratio between the sphere radius and the inner radius of the cylinder.

82. Dropping The Ball It was done in the 1840’s by Sir george gabriel stokes. He found what has becomeknown as stokes’ Law the drag force on a sphere of radius a moving through http://galileo.phys.virginia.edu/classes/152.mf1i.spring02/Stokes_Law.htm

Link to Previous Lecture Dropping the Ball (Slowly) Michael Fowler, UVa Stokes’ Law We’ve seen how viscosity acts as a frictional brake on the rate at which water flows through a pipe, let us now examine its frictional effect on an object falling through a viscous medium, to make it simple, we take a sphere. If we take a very viscous liquid, such as glycerin, and a small sphere, for example a ball bearing of diameter a few millimeters, it turns out experimentally that the liquid flows smoothly around the ball as it falls, with a flow pattern like: (The arrows show the fluid flow as seen by the ball. This smooth flow only takes place for fairly slow motion , as we shall see.) If we knew mathematically precisely how the velocity in this flow pattern varied near the ball, we could find the total viscous force on the ball by finding the velocity gradient near each little area of the ball’s surface, and doing an integral. But actually this is quite difficult. It was done in the 1840’s by Sir George Gabriel Stokes. He found what has become known as Stokes’ Law: the drag force on a sphere of radius a moving through a fluid of viscosity h at speed v is given by: F (drag) = 6 p a h v Note that this drag force is directly proportional to the radius That’s not obvious—one might have thought it would be proportional to the cross-section area, which would go as the square of the radius. The drag force is also

He also corresponded with an array of other important scientists such as George Fitzgerald, Hermann von Helmholtz, James Joule, James Clerk Maxwell and George Gabriel Stokes. Thomson was educated at Glasgow and Cambridge universities, and from 1846 until 1899 was professor of natural philosophy at Glasgow. He was elected a fellow of the Royal Society in 1851, knighted in 1866 and elevated to the peerage as Lord Kelvin in 1892. He died at his home near Largs in Ayrshire, Scotland, on 17 December 1907 at the age of 83 after a long and successful life.

87. Stokes’ Mistake In 1845 george gabriel stokes (18191903) sought to interpret the effect ofstellar aberration in terms of an ether that was totally dragged along with http://www.mathpages.com/home/kmath561/kmath561.htm

Stokes’ Mistake The original interpretation of stellar aberration when it was first discovered by Bradley was in terms of a corpuscular theory of light, but when the wave theory gained prominence in the 19 th century the explanation for stellar aberration became more difficult.  The basic problem was that no one knew if the putative luminiferous ether was immobile or participated in the motions of ordinary material objects.  On the assumption that it was just slightly dragged along by ordinary objects, Fresnel had given a fairly successful account of aberration and other first order optical phenomena, but many physicists were dissatisfied with the idea that the ether was so little affected by ordinary matter. Consider a portion of a plane wave, centered at the origin of xyz coordinates, with the normal pointing in the positive x direction as shown below. Since the wave is assumed to be propagating through the ether, and the ether itself is moving (relative to the frame of the quiescent background ether far from any bodies), the wavefront acquires additional components of velocity from the ether.  If the motion of the ether varies from place to place, it can have the effect of tilting the wavefronts.  To the first order the only significant effects are due to the component of the ether’s velocity in the direction of the wave propagation.  Thus, letting u = [u x ,u y ,u z ] denote the velocity vector of the ether, we will focus on the component u

Gabriel Stokes, rector of Skreen County Sligo , where he was born.

He retained his place on the foundation until , when on the day before his 84th birthday, he was elected to the mastership.

Money is the route of all evil.
