Define stokes law and reynold number ppt

Answer 1

Stokes’s law, mathematical equation that expresses thesettlingvelocities of small spherical particles in afluidmedium. The law, first set forth by the British scientist Sir George G.Stokes in 1851, is derived by consideration of the forces acting on a particular particle as it sinks through a liquid column under the influence of gravity

Answer 2

hola there,law stating that in fluorescence the wavelength of the emitted radiation is longer than that of the radiation causing it. This is not true in all cases

Reynolds numbers, where viscous forces are dominant, and is characterized by smooth, constant fluid motion; turbulent flow occurs at high Reynolds numbersand is dominated by inertial forces, which tend to produce chaotic eddies, vortices and other flow instabilities
